Check Digit Verification of cas no

The CAS Registry Mumber 157751-04-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,7,5 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 157751-04:
(8*1)+(7*5)+(6*7)+(5*7)+(4*5)+(3*1)+(2*0)+(1*4)=147
147 % 10 = 7
So 157751-04-7 is a valid CAS Registry Number.

Biomimetic semisynthesis of arglabin from parthenolide

Zhai, Jia-Dai,Li, Dongmei,Long, Jing,Zhang, Hao-Liang,Lin, Jian-Ping,Qiu, Chuan-Jiang,Zhang, Quan,Chen, Yue

, p. 7103 - 7107 (2012)

The semisynthesis of arglabin, an anticancer drug in clinical application, is developed from abundant natural product parthenolide via three steps. Each step in this sequence is highly stereoselective, and the substrate-dependent stereoselectivity in the epoxidation step can be explained by computational calculations. The success of chemical semisynthesis of arglabin suggests that the biosynthesis of arglabin might proceed in a similar pathway.
