Check Digit Verification of cas no

The CAS Registry Mumber 773109-21-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,3,1,0 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 773109-21:
(8*7)+(7*7)+(6*3)+(5*1)+(4*0)+(3*9)+(2*2)+(1*1)=160
160 % 10 = 0
So 773109-21-0 is a valid CAS Registry Number.

Catalytic enamines from dialkylamide-dialkylacetals

Davey, Roger M.,Stamford, N. Patrick J.

scheme or table, p. 2537 - 2539 (2012/06/30)

The formation of a transient enamine derived from DMF-DMA provides an effective alternative to the harsh conditions normally required for the nucleophilic addition of base-activated methylene compounds to a carbonyl group. Organocatalysts formed from dialkylamide-dialkylacetals in this manner may provide extensive synthetic utility for a number of well-established reactions in which the formation of enolates and enamines has been employed.
