Check Digit Verification of cas no

The CAS Registry Mumber 1122091-57-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,2,0,9 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1122091-57:
(9*1)+(8*1)+(7*2)+(6*2)+(5*0)+(4*9)+(3*1)+(2*5)+(1*7)=99
99 % 10 = 9
So 1122091-57-9 is a valid CAS Registry Number.

Preparation of optically active 1-O-alkyl-3-O-arylsulfonyl-sn-grycerol derivatives: Substrate engineering in enzyme-mediated enantioselective hydrolysis

Shimada, Yasutaka,Sato, Hiroshi,Mochizuki, Sachiyo,Matsumoto, Kazutsugu

scheme or table, p. 2981 - 2984 (2009/10/17)

Lipase PS catalyzes the enantioselective hydrolysis of various 2-acetyl compounds of the 1-O-alkyl-3-O-arylsulfonyl-sn-glycerol derivatives to afford the corresponding optically active compounds. Changing the structure of the 1-O-alkyl and 3-O-arylsulfonyl groups affects both the reactivity and enantioselectivity. Finally, the E value of the reaction for 2-acetyl-3-O-3,5-dimethylbenzenesulfonyl-1-O-4-methoxybenzyl-sn-glycerol is greater than 200. Georg Thieme Verlag Stuttgart.
