Check Digit Verification of cas no
The CAS Registry Mumber 21431-75-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,3 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21431-75:
(7*2)+(6*1)+(5*4)+(4*3)+(3*1)+(2*7)+(1*5)=74
74 % 10 = 4
So 21431-75-4 is a valid CAS Registry Number.

Direct Synthesis of β-Aminoenals through Reaction of 1,2,3-Triazine with Secondary Amines
Qui?ones, Ryan E.,Glinkerman, Christopher M.,Zhu, Kaicheng,Boger, Dale L.
, p. 3568 - 3571 (2017)
Simple and direct nucleophilic addition of secondary amines, including imidazole, to 1,2,3-triazine under mild reaction conditions (THF, 25-65 °C, 12-48 h), requiring no additives, cleanly provides β-aminoenals 4 in good yields (21 examples, 31-79%). The
