21076-38-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21076-38-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,7 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21076-38:
(7*2)+(6*1)+(5*0)+(4*7)+(3*6)+(2*3)+(1*8)=80
80 % 10 = 0
So 21076-38-0 is a valid CAS Registry Number.

, p. 1417 - 1423 (2007/10/03)
Reaction of 1,1-dialkylhydrazines with phenylisocyanate or phenylisothiocyanate yields stereo-specifically to the (EZ)-isomers of the corresponding 1,1-dialkyl-4-phenyl(thio)semicarbazides R1R2NNHC(=Z)NHPh (Z = O, S). In the NMR spec
