126740-47-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126740-47-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,7,4 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 126740-47:
(8*1)+(7*2)+(6*6)+(5*7)+(4*4)+(3*0)+(2*4)+(1*7)=124
124 % 10 = 4
So 126740-47-4 is a valid CAS Registry Number.

Enhanced Cyclization of N-Benzyloxycarbonyl-N-substituted Dipeptide Methyl Esters with Ammonia
Kawashiro, Katsuhiro,Nishiguchi, Kazuhisa,Kurosaka, Ikuo
, p. 2404 - 2406 (2007/10/02)
Cyclization of N,N'- dimethyl ester to the hydantoin derivative took place easily under mild ammonolysis conditions.Replacement of Z by p-methoxy-benzyloxycarbonyl also led to the cyclizatio
