Check Digit Verification of cas no
The CAS Registry Mumber 92622-81-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,6,2 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 92622-81:
(7*9)+(6*2)+(5*6)+(4*2)+(3*2)+(2*8)+(1*1)=136
136 % 10 = 6
So 92622-81-6 is a valid CAS Registry Number.

A highly efficient copper-catalyzed one-pot protocol is developed for the synthesis of 4-aminoquinazolines from easily available 2-iodo- or 2-bromobenzimidamides, aldehydes, and sodium azide. This one-pot approach proceeds via consecutive copper-catalyzed SNAr substitution, reduction, cyclization, oxidation and tautomerization. The corresponding target products (26 examples) are obtained in 50-90% yield.
