Check Digit Verification of cas no

The CAS Registry Mumber 78808-01-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,0 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78808-01:
(7*7)+(6*8)+(5*8)+(4*0)+(3*8)+(2*0)+(1*1)=162
162 % 10 = 2
So 78808-01-2 is a valid CAS Registry Number.

Novel Mannich Reaction of 8-Acetyl-7-hydroxy-4-methylcoumarin with 1-Arylpiperazines

Samant, S. D.,Deodhar, K. D.,Kulkarni, R. A.

, p. 215 - 217 (2007/10/02)

8-Acetyl-7-hydroxy-4-methylcoumarin (I) reacts with 1-arylpiperazines in the presence of excess paraformaldehyde to yield 4-methyl-9-(4-aryl-1-piperazinylmethyl)-2H,10H-8,9-dihydrobenzodipyran-2,10-diones, instead of the Mannich bases (II) or (III).The compounds show action on smooth muscles and act as agonists to the heart muscle receptors.
