Calculate Digit Verification of CAS Registry Number 109547-64:
(8*1)+(7*0)+(6*9)+(5*5)+(4*4)+(3*7)+(2*6)+(1*4)=140
140 % 10 = 0
So 109547-64-0 is a valid CAS Registry Number.

Studies with malononitrile derivatives: Synthesis and reactivity of 4-benzylpyrazole-3,5-diamine, 4-benzylisoxazole-3,5-diamine and thiazolidin-3-phenylpropanenitrile

Al-Mousawi, Saleh Mohammed,Moustafa, Moustafa Sherief,Elnagdi, Mohamed Hilmy

experimental part, p. 1371 - 1383 (2009/04/06)

Benzylmalononitrile 6 reacts with hydrazines, and hydroxylamine hydrochloride to yield the 4-benzylpyrazole-3,5-diamines 7 and 4-benzylisoxazol- e-3,5-diamine 9, respectively. Pyrazole-3,5-diamines 7 could be readily reacted with α,β-unsaturated nitriles
