Check Digit Verification of cas no

The CAS Registry Mumber 139575-15-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,7 and 5 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139575-15:
(8*1)+(7*3)+(6*9)+(5*5)+(4*7)+(3*5)+(2*1)+(1*5)=158
158 % 10 = 8
So 139575-15-8 is a valid CAS Registry Number.

A convenient procedure for the catalytic asymmetric 1,3-dipolar cycloaddition of azomethine ylides and alkenes

Alemparte, Carlos,Blay, Gonzalo,Jorgensen, Karl Anker

, p. 4569 - 4572 (2005)

(Chemical Equation Presented) Silver fluoride and cinchona alkaloids catalyze the diastereo- and enantioselective 1,3-dipolar cycloaddition between azomethine ylides, generated from N-alkylideneglycine esters, and acrylates to give the corresponding endo-adducts. Azomethine ylides derived from aromatic and aliphatic aldehydes react in a highly diastereoselective reaction with good yields and enantioselectivities of the substituted pyrrolidines.
