301309-00-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 301309-00-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,1,3,0 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 301309-00:
(8*3)+(7*0)+(6*1)+(5*3)+(4*0)+(3*9)+(2*0)+(1*0)=72
72 % 10 = 2
So 301309-00-2 is a valid CAS Registry Number.

, p. 424 - 433 (2007/10/03)
Substituted 5H-benzo[c]furo[3,2-g]chromen-5-ones, modified analogs of psoralen that contain a benzene ring annelated at the 5,6-position of a furo[3,2-g]chromen-7-one system, were synthesized from 3-hydroxy-6H-benzo[c] chromen-6-ones.
