314743-56-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 314743-56-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,4,7,4 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 314743-56:
(8*3)+(7*1)+(6*4)+(5*7)+(4*4)+(3*3)+(2*5)+(1*6)=131
131 % 10 = 1
So 314743-56-1 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,
