The CAS Registry Mumber 135085-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,0,8 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135085-19:
(8*1)+(7*3)+(6*5)+(5*0)+(4*8)+(3*5)+(2*1)+(1*9)=117
117 % 10 = 7
So 135085-19-7 is a valid CAS Registry Number.

Reaction of Tetracyanoethylene with Arylazoaminopyrazoles via Charge-Transfer Complexation

Hassan, Alaa A.,Ibrahim, Yusria R.,Mohamed, Nasr K.,Mourad, Aboul-Fetouh E.

, p. 1049 - 1053 (2007/10/02)

Arylazoaminopyrazoles (1a-e) react with tetracyanoethylene (TCNE) to yield pyrazolopyrimidines via charge-transfer (CT) complex formation.The effect of the substituents on the basicity of the pyrazole nucleus as well as the complexation centre in different types of pyrazoles is discussed.
