Check Digit Verification of cas no

The CAS Registry Mumber 64599-78-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,5,9 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 64599-78:
(7*6)+(6*4)+(5*5)+(4*9)+(3*9)+(2*7)+(1*8)=176
176 % 10 = 6
So 64599-78-6 is a valid CAS Registry Number.

A lipid-lipase aggregate with ether linkage as a new type of immobilized enzyme for enantio-selective hydrolysis in organic solvents

Akita,Umezawa,Matsukura,Oishi

, p. 318 - 324 (1992)

For the purpose of carrying out smoothly enzymatic reaction of water-insoluble substrates in organic solvents, a new type of immobilized enzyme, a lipid-lipase aggregate, was developed. In order to prepare various kinds of lipid-lipase aggregates, 27 kinds of dialkyl ether-type phospholipid analogues were newly synthesized and used for the preparation of aggregates with lipase. Thus obtained lipid-lipase aggregates were found to catalyze the enantioselective hydrolysis of the (+)-α-acyloxy ester 2 much more efficiently than lipase immobilized with synthetic prepolymer (ENTP-4000) in water-saturated isopropyl ether. Namely, the reaction time became much shorter (2 to 3 d for completion as compared with 21 d) and the chemical and optical yields of the reaction products were found to be high.
