87740-94-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87740-94-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,4 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 87740-94:
(7*8)+(6*7)+(5*7)+(4*4)+(3*0)+(2*9)+(1*4)=171
171 % 10 = 1
So 87740-94-1 is a valid CAS Registry Number.

A New Reaction of α-Nitro Nitriles: Conversion to β-Nitro Nitriles
Kornblum, Nathan,Singh, Haribansh K.,Boyd, Steven D.
, p. 358 - 362 (2007/10/02)
At room temperature the nitro group of an α-nitro nitrile is readily displaced by nitroparaffin anions with the result that β-nitro nitriles are produced in excellent yields.Evidence is presented for the view that these reactions are electron-transfer cha
