Check Digit Verification of cas no

The CAS Registry Mumber 1372925-35-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,9,2 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1372925-35:
(9*1)+(8*3)+(7*7)+(6*2)+(5*9)+(4*2)+(3*5)+(2*3)+(1*5)=173
173 % 10 = 3
So 1372925-35-3 is a valid CAS Registry Number.

Ionic nucleophilic catalysis of chiral ammonium betaines for highly stereoselective aldol reaction from oxindole-derived vinylic carbonates

Uraguchi, Daisuke,Koshimoto, Kyohei,Ooi, Takashi

supporting information; experimental part, p. 6972 - 6975 (2012/06/01)

A new strategy for developing stereoselective bond-forming reactions is introduced; it takes advantage of the ionic nucleophilic catalysis of chiral ammonium betaines to utilize vinylic esters simultaneously as the enolate precursor and the acylating agent for coupling with electrophiles. Its synthetic utility is clearly demonstrated by the realization of a highly diastereo- and enantioselective aldol reaction from oxindole-derived vinylic carbonates.
