56249-52-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56249-52-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,2,4 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 56249-52:
(7*5)+(6*6)+(5*2)+(4*4)+(3*9)+(2*5)+(1*2)=136
136 % 10 = 6
So 56249-52-6 is a valid CAS Registry Number.

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.
