883291-29-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 883291-29-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,3,2,9 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 883291-29:
(8*8)+(7*8)+(6*3)+(5*2)+(4*9)+(3*1)+(2*2)+(1*9)=200
200 % 10 = 0
So 883291-29-0 is a valid CAS Registry Number.

It has been established that the interaction of N1-(2- hydroxyphenylmethylthieno[2,3-b]pyrid-3-yl)arylamides with hydrazine hydrate leads to thieno[2,3-b]pyridine-2,3-diamines. It was shown that the reaction of the latter with acetylacetone and
