Check Digit Verification of cas no

The CAS Registry Mumber 1260015-77-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,0,1 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1260015-77:
(9*1)+(8*2)+(7*6)+(6*0)+(5*0)+(4*1)+(3*5)+(2*7)+(1*7)=107
107 % 10 = 7
So 1260015-77-7 is a valid CAS Registry Number.

Nickel-Catalyzed Asymmetric Addition of Aromatic Halides to Ketones: Highly Enantioselective Synthesis of Chiral 2,3-Dihydrobenzofurans Containing a Tertiary Alcohol

Li, Ying,Li, Wendian,Tian, Jiangyan,Huang, Guozheng,Lv, Hui

, p. 5353 - 5357 (2020/07/14)

A highly enantioselective and straightforward synthetic procedure to chiral 3-hydroxy-2,3-dihydrobenzofurans has been developed by nickel/bisoxazoline-catalyzed intramolecular asymmetric addition of aryl halides to unactivated ketones, giving 2,3-dihydrobenzofurans with a chiral tertiary alcohol at the C-3 position in good yields and excellent enantioselectivities (up to 92percent yield and 98percent ee). The gram-scale reaction also proceeded smoothly without a loss of yield and enantioselectivity.
