Check Digit Verification of cas no

The CAS Registry Mumber 1217275-19-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,2,7 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1217275-19:
(9*1)+(8*2)+(7*1)+(6*7)+(5*2)+(4*7)+(3*5)+(2*1)+(1*9)=138
138 % 10 = 8
So 1217275-19-8 is a valid CAS Registry Number.

Controlled ring-opening polymerization of lactide by bis-sulfonamide/ amine associations: Cooperative hydrogen bonding catalysis

Alba, Aurelie,Schopp, Aurelia,De Sousa Delgado, Anne-Paula,Cherif-Cheikh, Roland,MartiN-Vaca, Blanca,Bourissou, Didier

experimental part, p. 959 - 965 (2010/12/18)

The bis-sulfonamide m-C6H4(SO2NHPh) 2 efficiently promotes the ring-opening polymerization of lactide when combined with tertiary amines, such as N,N-dimethylamino-pyridine. Polylactides of controlled molecular weights (Mn up to 17,700 g moT-1) and very narrow molecular weight distributions (M w/Mn 2NHAr) moieties.
