Check Digit Verification of cas no

The CAS Registry Mumber 157496-70-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,4,9 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 157496-70:
(8*1)+(7*5)+(6*7)+(5*4)+(4*9)+(3*6)+(2*7)+(1*0)=173
173 % 10 = 3
So 157496-70-3 is a valid CAS Registry Number.

Synthesis of α,α-dialkoxy imines and α-keto acetals

De Kimpe,Stanoeva,Boeykens

, p. 427 - 431 (2007/10/02)

A convenient synthesis of monoacetals of α-diones, i.e. α-keto acetals, was developed by silver ion induced alcoholysis of regiospecifically formed α-bromo-α-chloro ketones. Similarly, the corresponding α,α-dialkoxy ketimines were synthesized from silver ion induced alcoholysis of α-bromo-α-chloro ketimines. Both methods provide an easy access to protected forms of α-diones, useful as building blocks in organic chemistry.
