91780-05-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91780-05-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,8 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91780-05:
(7*9)+(6*1)+(5*7)+(4*8)+(3*0)+(2*0)+(1*5)=141
141 % 10 = 1
So 91780-05-1 is a valid CAS Registry Number.

SYNTHESIS OF 4-PHENYLCOUMARINS FROM DALBERGIA VOLUBILIS AND EXOSTEMA CARIBAEUM
Bose, P.,Banerji, J.
, p. 2438 - 2439 (2007/10/02)
Two isomeric 4-phenyl coumarins, 3',7-dihydroxy-4',5-dimethoxy-4-phenylcoumarin (seshadrin) from Dalbergia volubilis and 3',5-dihydroxy-4',7-dimethoxy-4-phenylcoumarin from Exostema caribaeum have been synthesized.However, the spectral properties of the f
