Check Digit Verification of cas no

The CAS Registry Mumber 110198-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,1,9 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 110198-99:
(8*1)+(7*1)+(6*0)+(5*1)+(4*9)+(3*8)+(2*9)+(1*9)=107
107 % 10 = 7
So 110198-99-7 is a valid CAS Registry Number.

HIGHLY STEREOSELECTIVE METHOXYLATION AT THE SEVEN POSITION OF CEPHALOSPORINS

Tsuji, Teruji,Itani, Hikaru,Ishitobi, Hiroyuki

, p. 2745 - 2746 (2007/10/02)

Addition reaction of methanol to 7-methylsulfeniminocephem 1β-oxide derivatives (6 and 12) under acidic conditions gave exclusively 7β-amino-7α-methoxycephem 1β-oxides (7) stabilized by the formation of an intramolecular hydrogen bond between the 7β-amino and the oxygen atom at the 1-position.
