Check Digit Verification of cas no

The CAS Registry Mumber 931086-24-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,1,0,8 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 931086-24:
(8*9)+(7*3)+(6*1)+(5*0)+(4*8)+(3*6)+(2*2)+(1*4)=157
157 % 10 = 7
So 931086-24-7 is a valid CAS Registry Number.

Palladium-Catalyzed β-C-H Arylation of Alkyl Carboxamides with Sterically Hindered Aryl Iodides Using ortho-Sulfinyl Aniline Auxiliaries

Mu, Delong,Gao, Fang,Chen, Gong,He, Gang

, p. 1880 - 1885 (2017/08/14)

We disclose a pair of ortho-sulfinylaniline auxiliaries for palladium-catalyzed β-C-H arylation of alkyl carboxamides. Together, these auxiliaries offer a means to effect efficient β-methyl and methylene C-H bond arylation with sterically hindered aryl iodides. ortho-Methylsulfinylaniline (MSOA) enables efficient β-methyl C-H arylation of propanamide substrates with aryl iodides bearing various ortho-substituents including alkyl groups. ortho-Tosylsulfinylaniline (TSOA) enables β-methylene C-H arylation with ortho-substituted aryl iodides. Both amide-linked MSOA and TSOA auxiliaries can be easily removed to give ester products under relatively mild conditions.
