Check Digit Verification of cas no

The CAS Registry Mumber 1189954-07-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,9,5 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1189954-07:
(9*1)+(8*1)+(7*8)+(6*9)+(5*9)+(4*5)+(3*4)+(2*0)+(1*7)=211
211 % 10 = 1
So 1189954-07-1 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.
