Check Digit Verification of cas no

The CAS Registry Mumber 496945-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,6,9,4 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 496945-94:
(8*4)+(7*9)+(6*6)+(5*9)+(4*4)+(3*5)+(2*9)+(1*4)=229
229 % 10 = 9
So 496945-94-9 is a valid CAS Registry Number.

Sterically hindered lithium dialkylcuprates for the generation of highly functionalized mixed cuprates through a halogen-copper exchange

Piazza, Claudia,Knochel, Paul

, p. 3263 - 3265 (2002)

Even aldehyde and ketone functions are tolerated in mixed organocuprates prepared by copper-halogen exchange using (Me3CCH2)2CuLi (Neopent2CuLi) or (PhMe2CCH2)2CuLi (Neophyl2CuLi). The steric hindrance of the neopentyl and neophyl groups is essential to ensure the chemoselectivity of the reaction (see scheme), and therefore allows a general preparation of polyfunctionalized organocuprates.
