Check Digit Verification of cas no

The CAS Registry Mumber 157239-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,2,3 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 157239-55:
(8*1)+(7*5)+(6*7)+(5*2)+(4*3)+(3*9)+(2*5)+(1*5)=149
149 % 10 = 9
So 157239-55-9 is a valid CAS Registry Number.

KINETIC RESOLUTION OF RACEMIC GRIGNARD REAGENTS BY NICKEL-CATALYZED ASYMMETRIC GRIGNARD CROSS-COUPLING

Hayashi, Tamio,Kanehira, Koichi,Hioki, Tsuyoshi,Kumada, Makoto

, p. 137 - 140 (2007/10/02)

Racemic Grignard reagents, 2-phenylpropylmagnesium chloride and 2-norbornylmagnesium chloride were kinetically resolved by asymmetric cross-coupling with vinyl bromides in the presence of chiral phosphine-nickel catalysts to give optically active coupling products (ca. 37percent ee) and carboxylic acids after carbonation with carbon dioxide.
