329903-95-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 329903-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,9,9,0 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 329903-95:
(8*3)+(7*2)+(6*9)+(5*9)+(4*0)+(3*3)+(2*9)+(1*5)=169
169 % 10 = 9
So 329903-95-9 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.
