Check Digit Verification of cas no

The CAS Registry Mumber 194995-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,9,9 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 194995-43:
(8*1)+(7*9)+(6*4)+(5*9)+(4*9)+(3*5)+(2*4)+(1*3)=202
202 % 10 = 2
So 194995-43-2 is a valid CAS Registry Number.

Mono and bis double ester prodrugs of novel aminomethyl-THF 1β-methylcarbapenems

Lin, Yang-I.,Bitha, Panayota,Li, Zhong,Sakya, Subas M.,Strohmeyer, Timothy W.,Lang Jr., Stanley A.,Yang, Youjun,Bhachech, Niraja,Weiss, William J.,Petersen, Peter J.,Jacobus, Nilda V.,Bush, Karen,Testa, Raymond T.

, p. 1811 - 1816 (2007/10/03)

Mono and bis double ester prodrugs of aminomethyl THF 1β-methylcarbapenems 1 were Mono double ester derivatives (2, 4 and 7) did not demonstrate significantly improved oral activity due to the presence of the charged species. However, bis double ester derivatives (3 and 5) demonstrated enhanced oral activity.
