Check Digit Verification of cas no
The CAS Registry Mumber 61502-57-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,5,0 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 61502-57:
(7*6)+(6*1)+(5*5)+(4*0)+(3*2)+(2*5)+(1*7)=96
96 % 10 = 6

On the Preparation of Acyl Cyanides from Aldehydes
Haerle, Helmut,Jochims, Johannes C.
, p. 1400 - 1412 (2007/10/02)
The O-silylated cyanohydrins 3 prepared from the aldehydes 1 with trimethylsilyl cyanide are oxidized photochemically or thermally with N-bromosuccinimide to afford the acyl cyanides 4a-n.Scope and limitations of the procedure are discussed.
