Check Digit Verification of cas no

The CAS Registry Mumber 77380-01-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,8 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77380-01:
(7*7)+(6*7)+(5*3)+(4*8)+(3*0)+(2*0)+(1*1)=139
139 % 10 = 9
So 77380-01-9 is a valid CAS Registry Number.

SYNTHESIS AND PROPERTIES OF 7,7-DIAMINOQUINONE METHIDES

Pavlickova, Libuse,Vasickova, Sona,Soucek, Milan

, p. 2675 - 2683 (2007/10/02)

Diaminoquinone methides Xa-Xe were prepared by aminolysis of the dicyanoquinone methide IX.From the isolated intermediates XI and XIII a four-step mechanism was deduced, involving addition and elimination steps in the order Ad-E-Ad-E.Condensation of N,N,N',N'-tetramethylchloroformamidinium chloride with 2,6-ditert-butylphenol afforded bis(dimethylamino)-quinone methide Xc which on transamination was converted to the diaminoquinone methides Xa and Xb.Analysis of physico-chemical data of diaminoquinone methides leads to the conclusion that their structure can be represented by the zwitterionic formula XVII rather than the quinonoid formula X.
