100805-30-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 100805-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,8,0 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 100805-30:
(8*1)+(7*0)+(6*0)+(5*8)+(4*0)+(3*5)+(2*3)+(1*0)=69
69 % 10 = 9
So 100805-30-9 is a valid CAS Registry Number.

Synthesis of 8,9-Oxygenated 1-thiocoumestans
Reddy, B. Sucharita,Darbarwar, Malleshwar
, p. 556 - 559 (2007/10/02)
8,9-Dihydroxythiocoumestans (4; R=H, 2-chloro, 3-chloro, 2-methyl and 3-methyl) have been prepared by condensation of 4-hydroxy-1-thiocoumarins (1; 6-chloro, 7-chloro, 6-methyl and 7-methyl) with p-benzoquinone followed by acetylation and cyclisation.The
