Check Digit Verification of cas no

The CAS Registry Mumber 1224699-56-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,4,6,9 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1224699-56:
(9*1)+(8*2)+(7*2)+(6*4)+(5*6)+(4*9)+(3*9)+(2*5)+(1*6)=172
172 % 10 = 2
So 1224699-56-2 is a valid CAS Registry Number.

From the Feist-Bénary reaction to organocatalytic domino Michael-alkylation reactions: Asymmetric synthesis of 3(2H)-furanones

Dou, Xiaowei,Han, Xiaoyu,Lu, Yixin

supporting information; experimental part, p. 85 - 89 (2012/02/04)

It all adds up! A modified Feist-Bénary reaction employing a domino Michael-alkylation sequence was designed for the enantioselective synthesis of 3(2H)-furanones. L-Threonine-derived tertiary amine/thiourea catalysts were prepared for the first time; such catalysts promoted the designed domino Michael-alkylation reactions in a highly enantioselective manner (see scheme).
