Check Digit Verification of cas no

The CAS Registry Mumber 1040731-98-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,7,3 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1040731-98:
(9*1)+(8*0)+(7*4)+(6*0)+(5*7)+(4*3)+(3*1)+(2*9)+(1*8)=113
113 % 10 = 3
So 1040731-98-3 is a valid CAS Registry Number.

Enantiodivergent synthesis of trans-3,4-disubstituted succinimides by SmI2-mediated Reformatsky-type reaction

Lin, Geng-Jie,Luo, Shi-Peng,Zheng, Xiao,Ye, Jian-Liang,Huang, Pei-Qiang

, p. 4007 - 4010 (2008/09/20)

An enantiodivergent strategy for the synthesis of trans-3,4-disubstituted succinimides is reported. The key step is a highly trans-stereoselective SmI2-induced Reformatsky-type reaction of 4-substituted-O-benzoylated malimides with carbonyl compounds. Double chirality transmissions were performed with good to excellent diastereoselectivities.
