The CAS Registry Mumber 71996-37-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,9 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 71996-37:
(7*7)+(6*1)+(5*9)+(4*9)+(3*6)+(2*3)+(1*7)=167
167 % 10 = 7
So 71996-37-7 is a valid CAS Registry Number.

N',N'-DIALKYLIDENEUREAS

Fetyukhin, V. N.,Vovk, M. V.,Samarai, L. I.

, p. 1263 - 1271 (2007/10/02)

N',N'-Dialkylideneureas were obtained by the action of ketimines on α-chloroalkyl isocyanates.Their reactions with alcohols, amines, and proton-containing acids were investigated.It was shown that the reactions of N,N'-dialkylideneureas with phosphorus pentahalides and triphenyldibromophosphorane lead to N,N'-bis(α-halogenoalkyl)carbodiimides and α-halogenoalkyl isocyanates.
