Check Digit Verification of cas no

The CAS Registry Mumber 1045720-44-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,5,7,2 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1045720-44:
(9*1)+(8*0)+(7*4)+(6*5)+(5*7)+(4*2)+(3*0)+(2*4)+(1*4)=122
122 % 10 = 2
So 1045720-44-2 is a valid CAS Registry Number.

Yu, De-Sheng,Xu, Wei-An,Liu, Liang-Xian,Huang, Pei-Qiang

scheme or table, p. 1189 - 1192 (2009/04/06)

The first asymmetric synthesis of (-)-morusimic acid D, a 2,3-trans-2,6-cis-2-methyl-6-substituted piperidin-3-ol containing alkaloid is reported. The key steps are the reductive alkylation of N,O-diprotected 3-hydroxyglutarimide, a stepwise reductive alkylation, and an asymmetric aldol-type reaction using a modified Evans chiral auxiliary.
