Check Digit Verification of cas no

The CAS Registry Mumber 156636-17-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,6,3 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 156636-17:
(8*1)+(7*5)+(6*6)+(5*6)+(4*3)+(3*6)+(2*1)+(1*7)=148
148 % 10 = 8
So 156636-17-8 is a valid CAS Registry Number.

Convenient synthesis of primary selenoamides from aryl nitriles, selenium and sodium borohydride

Zhao,Ruan,Fan,Zhou

, p. 1761 - 1765 (1994)

Aryl nitriles react smoothly with sodium hydrogen selenide, itself prepared in situ from selenium and sodium borohydride, in ethanol to give the corresponding primary selenoamides in moderate to good yield.

Synthesis of primary arylselenoamides by reaction of aryl nitriles with Woollins' reagent

Hua, Guoxiong,Li, Yang,Slawin, Alexandra M. Z.,Woollins, J. Derek

, p. 5251 - 5254 (2007/10/03)

The reaction of aryl nitriles with Woollins' reagent followed by water affords a variety of primary arylselenoamides In 60-100% yield. The first crystal structures of two primary selenoamides are reported.
