Check Digit Verification of cas no
The CAS Registry Mumber 13114-62-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,1 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13114-62:
(7*1)+(6*3)+(5*1)+(4*1)+(3*4)+(2*6)+(1*2)=60
60 % 10 = 0
So 13114-62-0 is a valid CAS Registry Number.

The convenient preparation of N2-unprotected five-membered cyclic guanidines was achieved through a cascade [3 + 2] cycloaddition between organo-cyanamides and α-haloamides under mild conditions in good to excellent yields (up to 99%). The corresponding cyclic guanidines could be easily transformed into hydantoins via hydrolysis.
