Check Digit Verification of cas no

The CAS Registry Mumber 22114-29-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,1 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 22114-29:
(7*2)+(6*2)+(5*1)+(4*1)+(3*4)+(2*2)+(1*9)=60
60 % 10 = 0
So 22114-29-0 is a valid CAS Registry Number.

Metal-free cascade synthesis of unsymmetrical 2-aminopyrimidines from imidazolate enaminones

Cui, Xue,Li, Youbin,Ma, Jianting,Wang, Xuesong,Xu, Junyu,Zeng, Tingting

, p. 24247 - 24253 (2021/07/29)

A convenient metal-free synthesis of unsymmetrical 2-aminopyrimidines from imidazolate enaminones has been developed. In this procedure, various structural 2-aminopyrimidines, as well as 4,5-dihydroisoxazol-5-ols and pyrazoles were synthesized in moderate to excellent yields. A plausible mechanism was also proposed for the cascade reaction. This method represents an effective strategy towards the synthesis of unsymmetrical 2-aminopyrimidines.
