Check Digit Verification of cas no

The CAS Registry Mumber 98394-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,3,9 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 98394-18:
(7*9)+(6*8)+(5*3)+(4*9)+(3*4)+(2*1)+(1*8)=184
184 % 10 = 4
So 98394-18-4 is a valid CAS Registry Number.

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

De Kimpe,Stanoeva,Boeykens

, p. 427 - 431 (1994)

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.
