162378-41-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 162378-41-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,3,7 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 162378-41:
(8*1)+(7*6)+(6*2)+(5*3)+(4*7)+(3*8)+(2*4)+(1*1)=138
138 % 10 = 8
So 162378-41-8 is a valid CAS Registry Number.

Activated Nitriles in Heterocyclic Synthesis: Synthesis of Several New 2-Substituted Pyrano-1,2,4-triazolopyrimidine Derivatives
El-Agrody, Ahmed M.,Hassan, Saber M.
, p. 100 - 101 (2007/10/03)
A naphthopyranopyrimidine was synthesized via hydrazinolysis of a 2-ethoxymethylideneaminonaphthopyran; polysubstituted pyrano-1,2,4-triazolopyrimidines were also prepared.
