319491-25-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 319491-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,9,4,9 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 319491-25:
(8*3)+(7*1)+(6*9)+(5*4)+(4*9)+(3*1)+(2*2)+(1*5)=153
153 % 10 = 3
So 319491-25-3 is a valid CAS Registry Number.

New version of multicomponent condensation leading to 3-amino-2-acyl-4,5,6-trimethylthieno[2,3-b]pyridines
Dyachenko
, p. 1578 - 1583 (2015/12/30)
3-Amino-2-acyl-4,5,6-trimethylthieno[2,3-b]pyridines were synthesized by multicomponent condensation of acetaldehyde, cyanothioacetamide, 4-(but-2-en-2-yl)-morpholine, and a-haloketones.
