Check Digit Verification of cas no

The CAS Registry Mumber 1131849-80-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,1,8,4 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1131849-80:
(9*1)+(8*1)+(7*3)+(6*1)+(5*8)+(4*4)+(3*9)+(2*8)+(1*0)=143
143 % 10 = 3
So 1131849-80-3 is a valid CAS Registry Number.

Efficient synthesis of optically active gallocatechin-3-gallate derivatives via 6-endo-cyclization

Hirooka, Yasuo,Nitta, Mariko,Furuta, Takumi,Kan, Toshiyuki

scheme or table, p. 3234 - 3238 (2009/06/18)

Optically active dihydrobenzopyran derivatives are synthesized by 6-endo cyclization of corresponding epoxy-phenol, which is readily derived from the enantioselective epoxidation of 1,3-diarylpropene. Synthetic dihydrobenzopyrans are converted into (-)-5,7-dideoxy-gallocatechin gallate as well as (-)-5,7-dideoxy-epigallocatechin derivative. Georg Thieme Verlag Stuttgart.
