Check Digit Verification of cas no

The CAS Registry Mumber 189072-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,7 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 189072-85:
(8*1)+(7*8)+(6*9)+(5*0)+(4*7)+(3*2)+(2*8)+(1*5)=173
173 % 10 = 3
So 189072-85-3 is a valid CAS Registry Number.

Novel C-2 substituted carbapenem derivatives. Part III. Synthesis and biological activity of 2-(functionalised ethenyl, oxyiminomethyl and α-[hydroxyl benzyl)-carbapenems

Clear, Nicola J. C.,Davies, John S.,Eglington, A. John,Fell, Stephen C. M.,Hinks, Jeremy D.,Hird, Nicholas W.,Hunt, Eric,Moss, Stephen F.,Pearson, Michael J.

, p. 237 - 245 (1997)

The synthesis, antibacterial activity and stability to human dehydropeptidase-1 (DHP-1) of three small series of carbapenems carrying carbon-linked substituents at C-2 are described. C-2 Ethenyl carbapenems showed moderate antibacterial activity but poor stability to DHP-1. C-2 Oxyiminomethyl carbapenems demonstrated variable activity and stability. C-2 α-(Hydroxy)benzyl carbapenems were the most promising and showed good potency and DHP-1 stability.
