Check Digit Verification of cas no
The CAS Registry Mumber 185987-41-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,9,8 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 185987-41:
(8*1)+(7*8)+(6*5)+(5*9)+(4*8)+(3*7)+(2*4)+(1*1)=201
201 % 10 = 1
So 185987-41-1 is a valid CAS Registry Number.

Simple preparation of aryl telluroesters and (2Z)-β-(aryltelluro) cinnamic esters
Zhao, Chang-Qiu,Huang, Xian
, p. 249 - 255 (2007/10/03)
Simple preparation of aryl telluroesters from reaction of tellurium powder and aryl Grignard reagents then acylation with acyl chlorides. Addition of telluroesters to arylpropiolates gave (2Z)-β-aryltelluro-α,β-unsaturated esters with high stereoselectivity.
