Check Digit Verification of cas no

The CAS Registry Mumber 1316815-11-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,6,8,1 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1316815-11:
(9*1)+(8*3)+(7*1)+(6*6)+(5*8)+(4*1)+(3*5)+(2*1)+(1*1)=138
138 % 10 = 8
So 1316815-11-8 is a valid CAS Registry Number.

Synthesis of [2H5]-ebastine fumarate and [ 2H5]-hydroxyebastine

Yu, Zhoujie,Wang, Wei,Chen, Liqin

, p. 352 - 356 (2012/06/01)

This study describes the synthesis of deuterium-labelled ebastine fumarate and its deuterium-labelled metabolite hydroxyebastine. The synthesis of the two desired compounds both used [2H5]-bromodiphenylmethane as deuterium-labelled reagent, which was synthesized beforehand in three steps. [2H5]-ebastine was synthesized in further three steps with a 27% overall yield and [2H5]-hydroxyebastine was synthesized in further seven steps with a 13% overall yield.
