2638-57-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2638-57-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,3 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2638-57:
(6*2)+(5*6)+(4*3)+(3*8)+(2*5)+(1*7)=95
95 % 10 = 5
So 2638-57-5 is a valid CAS Registry Number.

7-Dehydrocholesterol reductase activity is independent of cytochrome P450 reductase

Zou, Ling,Li, Li,Porter, Todd D.

experimental part, p. 435 - 438 (2012/04/23)

7-Dehydrocholesterol reductase (DHCR7) catalyzes the final step in cholesterol synthesis. The enzyme utilizes NADPH as a source of electrons and has been reported to require NADPH-cytochrome P450 reductase (POR) as its redox partner. To test this hypothes

Process for recovery of plant sterols from by-product of vegetable oil refining

-

Page/Page column 5-6, (2008/06/13)

The process for recovery of plant sterols and tocopherols from deodorization distillates formed during chemical or physical refining of vegetable oils consists of the following steps: free fatty acids are removed from the deodorization distillate by vacuum distillation or by continuation solvent saponification, after the removal of free fatty acids, the received material is reacted with an aromatic carboxylic acid anhydride at a temperature of 50-150° C., under reduced pressure, after the treatment with anhydride, tocopherols are removed from the mixture, and crystalline free sterols are recovered from the distillation residue containing sterol esters, di- and triglycerides by transesterification.
