Check Digit Verification of cas no

The CAS Registry Mumber 246519-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,6,5,1 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 246519-33:
(8*2)+(7*4)+(6*6)+(5*5)+(4*1)+(3*9)+(2*3)+(1*3)=145
145 % 10 = 5
So 246519-33-5 is a valid CAS Registry Number.

Convergent syntheses of oral THF 1β-methylcarbapenems

Bitha, Panayota,Li, Zhong,Lin, Yang-I

, p. 643 - 648 (2007/10/03)

Convergent syntheses of oral THF 1β-methylcarbapenems 4 (OCA-983) and 5 starting from M2-phosphate 1 were developed. Reaction of the M2-phosphate 1 with THF thiols containing a requisite prodrug side chain, 9 and 10, gave the desired oral THF 1β-methylcarbapenems 4 and 5, respectively, in 46% and 42% overall yields.
