Check Digit Verification of cas no

The CAS Registry Mumber 416852-46-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,6,8,5 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 416852-46:
(8*4)+(7*1)+(6*6)+(5*8)+(4*5)+(3*2)+(2*4)+(1*6)=155
155 % 10 = 5
So 416852-46-5 is a valid CAS Registry Number.

Cyclopenta[g]quinazoline-based antifolates: The effect of the chirality at the 6-position on the inhibition of thymidylate synthase (TS)

Bavetsias,Marriott,Theti,Melin,Wilson,Jackman

, p. 3015 - 3017 (2001)

Cyclopenta[g]quinazoline-based inhibitors of thymidylate synthase (TS) possess a chiral centre at the 6-position of the molecule. The effect of this chirality on the inhibition of TS was investigated by synthesising compounds 6S-1a-c, 6R-1a-c. It was shown, in particular with the diastereoisomers 6S-1c, 6R-1c, that the inhibitory activity against TS is mainly due to the 6S diastereoisomer rather than the 6R diastereoisomer, which is virtually inactive.
