71055-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71055-91-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,5 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 71055-91:
(7*7)+(6*1)+(5*0)+(4*5)+(3*5)+(2*9)+(1*1)=109
109 % 10 = 9
So 71055-91-9 is a valid CAS Registry Number.

Carbodiimides (15) of type H-C-N=C=N-R react with N-bromosuccinimide (NBS) to afford unstable alkylidenecyanamidium bromides (18) which undergo von Braun elimination of R-Br giving the alkylidenecyanamides 19 if R is a tertiary alkyl group.Reaction of car
