Check Digit Verification of cas no

The CAS Registry Mumber 1326231-62-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,6,2,3 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1326231-62:
(9*1)+(8*3)+(7*2)+(6*6)+(5*2)+(4*3)+(3*1)+(2*6)+(1*2)=122
122 % 10 = 2
So 1326231-62-2 is a valid CAS Registry Number.

Organocatalytic domino double Michael reaction of ethyl (E)-7-oxohept-2-enoate and ,-unsaturated aldehydes: Efficient asymmetric synthesis of cyclohexanes with four contiguous stereocenters

Hong, Bor-Cherng,Sadani, Amit A.,Nimje, Roshan Y.,Dange, Nitin S.,Lee, Gene-Hsiang

supporting information; experimental part, p. 1887 - 1895 (2011/08/05)

Organocatalytic domino double Michael reactions of ethyl (E)-7-oxohept-2-enoate and ,-unsaturated aldehydes provided ethyl 2-(2,4-diformyl-3-phenylcyclohexyl)acetate with excellent diastereoselectivities (>20:1 dr) and enantioselectivities (>99% ee). The adducts were further transformed to octahydro-3H-2-benzopyran-3-ones, octahydroisoquinolin-3(2H)- ones, and decahydro-5H-oxazolo[2,3-a]isoquinolin-5-ones.
