1372776-06-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1372776-06-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,7,7 and 6 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1372776-06:
(9*1)+(8*3)+(7*7)+(6*2)+(5*7)+(4*7)+(3*6)+(2*0)+(1*6)=181
181 % 10 = 1
So 1372776-06-1 is a valid CAS Registry Number.

Synthesis of cyclic guanidines: 2-arylamino-1,4,5,6-tetrahydropyrimidines
Shaw, Julian W.,Grayson, David H.,Rozas, Isabel
, p. 161 - 174 (2014/03/21)
Considering the biological and chemical relevance of guanidine containing derivatives, we have devised a novel and efficient two-step synthesis of 2-arylamino-1,4,5,6-tetrahydropyrimidines. We have found that the coupling of aryl bromides with 2-aminopyri
