87963-46-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87963-46-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,6 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 87963-46:
(7*8)+(6*7)+(5*9)+(4*6)+(3*3)+(2*4)+(1*6)=190
190 % 10 = 0
So 87963-46-0 is a valid CAS Registry Number.

Adducts formed by some 1,4-Benzoquinones in Liquid Ammonia
Chudek, John A.,Foster, Roy,Reid, Francis J.
, p. 726 - 727 (1983)
N.m.r. spectra of fresh solutions of 1,4-benzoquinone and various, mainly chloro-substituted, derivatives in liquid ammonia are consistent with nucleophilic addition at one or both carbonyl atoms and not at C(2), or equivalent positions, expected in Michael-type addition.
