Check Digit Verification of cas no

The CAS Registry Mumber 1228172-16-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,1,7 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1228172-16:
(9*1)+(8*2)+(7*2)+(6*8)+(5*1)+(4*7)+(3*2)+(2*1)+(1*6)=134
134 % 10 = 4
So 1228172-16-4 is a valid CAS Registry Number.

Tunable bromomagnesium thiolate tishchenko reaction catalysts: Intermolecular aldehyde-trifluoromethylketone coupling

Cronin, Linda,Manoni, Francesco,O'Connor, Cornelius J.,Connon, Stephen J.

, p. 3045 - 3048 (2010)

(Figure Presented) Applied knowledge: A new thiolate-catalyzed Tishchenko reaction inspired by biochemical processes features exceptionally good control over the catalyst's steric/electronic properties. The isolation of reaction intermediates provided valua-ble insights into the reaction mechanism, which in turn has allowed the development of the first cross-Tishchenko coupling reactions between aldehydes and activated ketones (see example).
