79280-20-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79280-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,2,8 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 79280-20:
(7*7)+(6*9)+(5*2)+(4*8)+(3*0)+(2*2)+(1*0)=149
149 % 10 = 9
So 79280-20-9 is a valid CAS Registry Number.

Reaction of Hydrazine Hydrate on Some Coumarins
Bakre, K. M.,Merchant, J. R.
, p. 614 - 615 (2007/10/02)
The reaction of hydrazine hydrate with coumarin derivatives having a heterocyclic ring in the 3,4-position of the coumarin has been found to give hydrazino derivatives (II, IV, VI and VIII).For the formation of the latter, it is necessary to have a hetero
