Check Digit Verification of cas no

The CAS Registry Mumber 72625-01-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,2 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72625-01:
(7*7)+(6*2)+(5*6)+(4*2)+(3*5)+(2*0)+(1*1)=115
115 % 10 = 5
So 72625-01-5 is a valid CAS Registry Number.

Convenient heterocyclization reactions with ethyl 2-amino-4,5,6,7-tetrahydrobenzo[b] thiophene-3-carboxylate: Synthesis of pyrazole, isoxazole and pyridazine

Wardakhan, Wagnat Wahba

, p. 275 - 293 (2000)

The ethyl 2-diazo-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate 2 reacts with ethyl acetoacetate to give the hydrazone derivative 4. The reactivity of 4 towards a number of different reagents including active methylene compounds as well as the use of 4 to synthesize fused heterocyclic systems is described.
