Check Digit Verification of cas no

The CAS Registry Mumber 1111644-91-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,1,6,4 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1111644-91:
(9*1)+(8*1)+(7*1)+(6*1)+(5*6)+(4*4)+(3*4)+(2*9)+(1*1)=107
107 % 10 = 7
So 1111644-91-7 is a valid CAS Registry Number.

Stereodivergency of triazolium and imidazolium-derived NHcs for catalytic, enantioselective cyclopentane synthesis

Kaeobamrung, Juthanat,Bode, Jeffrey W.

, p. 677 - 680 (2009)

(Chemical Equation Presented) Chiral triazolium- and imidazolium-derived N-heterocyclic carbene catalysts promote the direct annulation of α,β-unsaturated aldehydes and achiral α-hydroxy enones to afford cyclopentane-fused lactones with high enantioselect
