Check Digit Verification of cas no

The CAS Registry Mumber 82952-89-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,5 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 82952-89:
(7*8)+(6*2)+(5*9)+(4*5)+(3*2)+(2*8)+(1*9)=164
164 % 10 = 4
So 82952-89-4 is a valid CAS Registry Number.

Discovery of dipeptide-derived catalysts for the enantioselective addition of dimethylzinc to aldehydes

Kang, Seock Yong,Park, Yong Sun

, p. 1703 - 1706 (2012)

A new class of modular chiral catalysts derived from various amino acid-L-Pro dipeptides was prepared, and the catalysts were tested for their ability to catalyze the enantioselective addition of dimethylzinc to aromatic aldehydes. Dipeptides derived from L-Asp-L-Pro were identified as effective catalysts for the addition at room temperature with up to 97:3er and 95% yield.
