Check Digit Verification of cas no

The CAS Registry Mumber 101109-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,1,0 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 101109-89:
(8*1)+(7*0)+(6*1)+(5*1)+(4*0)+(3*9)+(2*8)+(1*9)=71
71 % 10 = 1
So 101109-89-1 is a valid CAS Registry Number.

A high-yielding protocol for the synthesis of 4,5-diarylpyrimidin-2-amine derivatives from chalcones

Kooramatom Unni, Krishnaraj,Menon, Prasanth K.,George, Scholly Clair,Thomas, Sajesh P.,Devaky

, p. 112 - 118 (2021/10/07)

A novel, high yielding and versatile protocol was achieved for the synthesis of 4,5-diaryl-2-pyrimidinamine derivatives from chalcones. The synthesis was accomplished by converting the chalcones into 3-chloro-2,3-diaryl-2-propen-1-ones followed by subsequent reaction with amidine derivatives.
