Check Digit Verification of cas no

The CAS Registry Mumber 503306-84-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,3,0 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 503306-84:
(8*5)+(7*0)+(6*3)+(5*3)+(4*0)+(3*6)+(2*8)+(1*4)=111
111 % 10 = 1
So 503306-84-1 is a valid CAS Registry Number.

Modified coumarins. 4. Synthesis and biological properties of cyclopentane-annelated furocoumarins

Garazd,Garazd,Shilin,Panteleimonova,Khilya

, p. 230 - 242 (2007/10/03)

Psoralen and allopsoralen analogs that contain an annelated cyclopentane were synthesized from 7-hydroxy- and 9-hydroxy-1,2,3,4-tetrahydrocyclopenta[c]chromen-4-ones. 9-Phenyl-1,2,3,4-tetrahydrocyclopenta[c]furo[3,2-g]chromen-4-one exhibited low toxicity,
