Check Digit Verification of cas no

The CAS Registry Mumber 157609-76-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,6,0 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 157609-76:
(8*1)+(7*5)+(6*7)+(5*6)+(4*0)+(3*9)+(2*7)+(1*6)=162
162 % 10 = 2
So 157609-76-2 is a valid CAS Registry Number.

(N-Methylphenylsulfoximidoyl)methyllithium: A versatile reagent for the determination of absolute configuration of six-membered ring ketones

Preite,Gonzalez-Sierra,Zinczuk,Ruveda

, p. 503 - 506 (2007/10/02)

The diastereotopic chemical shift differences of the 1H and 13C NMR signals of the adducts formed by addition of (N-methylphenylsulfoximidoyl)methyllithium (2) to cyclic ketones has been studied. The stereodifferentiation of the proton and carbon atoms follow a very regular pattern annd the rule that can be drawn provides an alternative and complementary method to earlier procedures for the determinations of absolute configuration of six-membered ring ketones.
