Check Digit Verification of cas no

The CAS Registry Mumber 177167-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,1,6 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 177167-80:
(8*1)+(7*7)+(6*7)+(5*1)+(4*6)+(3*7)+(2*8)+(1*0)=165
165 % 10 = 5
So 177167-80-5 is a valid CAS Registry Number.

Platelet activating factor derivative and synthesis method thereof

-

, (2017/08/29)

The invention belongs to the technical field of chemical synthesis and discloses a platelet activating factor derivative with a formula (I) structure, wherein a substituent group R refers to an acryl group. A synthetic route includes nine-step reaction by taking chiral source S-configuration solketal as a starting reactant. The method is adopted for synthesis of a 2-sulfo platelet activating factor and a derivative thereof for the first time and has advantages of high yield, easiness in separation and the like. Low-cost batch synthesis of 2-S-PAF and the derivative thereof is realized, and significances to activity research of 2-S-PAF and the derivative thereof, biological experiments, clinical application and disease treatment are achieved.
