Check Digit Verification of cas no

The CAS Registry Mumber 1021949-26-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,9,4 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1021949-26:
(9*1)+(8*0)+(7*2)+(6*1)+(5*9)+(4*4)+(3*9)+(2*2)+(1*6)=127
127 % 10 = 7
So 1021949-26-7 is a valid CAS Registry Number.

Enantioselective trimethylsilylcyanation of benzaldehyde using pyrrolidine-based chiral salen ligands

Serra, M. Elisa Silva,Murtinho, Dina,Goth, Albertino

scheme or table, p. 64 - 69 (2010/08/07)

The in situ formed Ti(IV) complexes of several pyrrolidine-based chiral salen ligands derived from natural (L)-tartaric acid were evaluated as catalysts in the enantioselective trimethylsilylcyanation of benzaldehyde. The catalysts were found to be very active, producing the corresponding product, O-trimethylsilylmandelonitrile, in high yields (>94%) and enantioselectivities of up to 88%.
