79598-26-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79598-26-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,5,9 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 79598-26:
(7*7)+(6*9)+(5*5)+(4*9)+(3*8)+(2*2)+(1*6)=198
198 % 10 = 8
So 79598-26-8 is a valid CAS Registry Number.

, p. 538 - 542 (2007/10/02)
Cyclodehydration of 2-carboxymethylmercaptothienopyrimidin-4(3H)-ones (IV) have been studied.IV (R3=R4=Ph and R3=Me,R4=Ph) on reaction with acetic anhydride and pyridine mixture readily yield stable fusedring mesoionic systems (VI).While IV (R3=Ph,
