Check Digit Verification of cas no

The CAS Registry Mumber 31408-22-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,0 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 31408-22:
(7*3)+(6*1)+(5*4)+(4*0)+(3*8)+(2*2)+(1*2)=77
77 % 10 = 7
So 31408-22-7 is a valid CAS Registry Number.

Palladium-catalyzed remote C-H functionalization of 2-aminopyrimidines

Das, Animesh,Jana, Akash,Maji, Biplab

, p. 4284 - 4287 (2020)

A straightforward strategy was developed for the arylation and olefination at the C5-position of the N-(alkyl)pyrimidin-2-amine core with readily available aryl halides and alkenes, respectively. This approach was highly regioselective, and the transformation was achieved based on two different (Pd(ii)/Pd(iv)) and (Pd(0)/Pd(ii)) catalytic cycles.
