Check Digit Verification of cas no

The CAS Registry Mumber 188240-69-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,2,4 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 188240-69:
(8*1)+(7*8)+(6*8)+(5*2)+(4*4)+(3*0)+(2*6)+(1*9)=159
159 % 10 = 9
So 188240-69-9 is a valid CAS Registry Number.

Replacement of the 1',4'-phenylene region in 5,10-dideaza-5,6,7,8-tetrahydrofolic acid (DDATHF) by 4,5,6,7-tetrahydrobenzo[c]thiophene and 4,5,6,7-tetrahydroisobenzofuran nuclei

Taylor,Dowling

, p. 1599 - 1603 (1997)

Two new analogs of DDATHF, in which the 1',4'-phenylene unit is replaced by 4,5,6,7-tetrahydrobenzo[c]thiophene and 4,5,6,7-tetrahydroisobenzofuran nuclei, have been prepared and evaluated for in vitro cytotoxicity, GARFT inhibition, and FPGS affinity as potential antitumor agents.
