Check Digit Verification of cas no

The CAS Registry Mumber 143998-62-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,9 and 8 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143998-62:
(8*1)+(7*4)+(6*3)+(5*9)+(4*9)+(3*8)+(2*6)+(1*2)=173
173 % 10 = 3
So 143998-62-3 is a valid CAS Registry Number.

VICARIOUS NUCLEOPHILIC SUBSTITUTION OF HYDROGEN IN PYRIDAZINES

Ostrowicz, Andrzej,Baloniak, Sylwester,Makosza, Mieczyslaw,Rykowski, Andrzej

, p. 4787 - 4790 (2007/10/02)

Pyridazines, 3-pyridazinones and 3,6-pyridazinediones readily undergo vicarious nucleophilic substitution of hydrogen (VNS) with carbanion of chloromethyl p-tolyl sulfone to form new carbon-carbon bonds.The reaction offers a novel approach to the synthesi
