Check Digit Verification of cas no

The CAS Registry Mumber 776297-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,6,2,9 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 776297-01:
(8*7)+(7*7)+(6*6)+(5*2)+(4*9)+(3*7)+(2*0)+(1*1)=209
209 % 10 = 9
So 776297-01-9 is a valid CAS Registry Number.

Catalytic asymmetric construction of C-4 alkenyl substituted pyrazolone derivatives bearing multiple stereoelements

Qu, Jingping,Wang, Baomin,Wang, Wenyao,Wei, Shiqiang,Zhang, Wande

supporting information, p. 6550 - 6553 (2021/07/07)

An organocatalytic asymmetric process was reported for the sterically precise construction of C-4 alkenyl substituted pyrazolone derivatives bearing multiple stereoelements. A series of interesting products featuring the union of a centrally chiral pyrazolone moiety and an axially chiral styrene unit were obtained in high yield with excellent diastereoselectivity and enantioselectivity (up to 99% ee, >20?:?1 dr). The process has the characteristics of mild reaction conditions, simple operation and broad substrate scope. The result of gram-scale reaction indicates that the reaction has good practicability.

-

Paragraph 0069-0072, (2018/05/01)

The invention discloses a method for preparing an alpha-alkyl-beta-ketone ester compound shown as a formula (I). The method comprises the following steps: a 1,4-dihydropyridine ester compound shown asa formua (III) is taken as a reducing agent, and under existence of a Lewis acid catalyst, a compound in a formula (II) is subjected to a reduction reaction to obtain the alpha-alkyl-beta-ketone ester compound shown as the formula (I). The method has the advantages of simple operation, mild condition and environmental protection, and is suitable for a plurality of substrates, and the yield can reach as highest as 95%. By using the method of the invention, a plurality of alpha-alkyl-beta-ketone ester compounds can be efficiently prepared, types of medical intermediates are enriched, and the method has an excellent industrial application prospect.

Heck reaction of Baylis-Hillman adducts with iodobenzenes using a catalytic amount of Pd/C under solvent-free conditions

Kim, Hyun-Soo,Lee, Sang-Jin,Choi, Boram,Yoon, Cheol Min

, p. 3161 - 3164 (2012/11/13)

The reaction of Baylis-Hillman adducts with iodobenzenes using commercially available palladium-on-carbon as a catalyst under solvent-free conditions afforded the corresponding coupling products, α-benzyl-β-keto esters, in high to excellent yields. The reactions are very efficient.
