Check Digit Verification of cas no
The CAS Registry Mumber 41890-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,8,9 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 41890-17:
(7*4)+(6*1)+(5*8)+(4*9)+(3*0)+(2*1)+(1*7)=119
119 % 10 = 9
So 41890-17-9 is a valid CAS Registry Number.

Ureas from N-Chloroamidines; An Aza-Analogous Hofmann Degradation
Sonnenschein, Helmut,Schmitz, Ernst
, p. 443 - 444 (2007/10/02)
N-Chlorination and subsequent treatment with alkali of suitably substituted benzamidines yields ureas with phenyl or alkyl migration.Under the same conditions, 2-iminopyrrolidine is converted into 2-oxohexahydropyrimidine with ring enlargement.
