889954-06-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 889954-06-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,9,9,5 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 889954-06:
(8*8)+(7*8)+(6*9)+(5*9)+(4*5)+(3*4)+(2*0)+(1*6)=257
257 % 10 = 7
So 889954-06-7 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
