74332-63-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74332-63-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,3,3 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74332-63:
(7*7)+(6*4)+(5*3)+(4*3)+(3*2)+(2*6)+(1*3)=121
121 % 10 = 1
So 74332-63-1 is a valid CAS Registry Number.

Treatment of C-substituted ternary maleisoimidium perchlorates (5),(18), and (24) with sodium azide gave the corresponding maleamic acid azides, which on heating underwent a Curtius rearrangement, followed by electrocyclisation, to yield 6-dialkylamino-de
