79587-91-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79587-91-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,5,8 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 79587-91:
(7*7)+(6*9)+(5*5)+(4*8)+(3*7)+(2*9)+(1*1)=200
200 % 10 = 0
So 79587-91-0 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,
