Check Digit Verification of cas no

The CAS Registry Mumber 1280722-63-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,7,2 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1280722-63:
(9*1)+(8*2)+(7*8)+(6*0)+(5*7)+(4*2)+(3*2)+(2*6)+(1*3)=145
145 % 10 = 5
So 1280722-63-5 is a valid CAS Registry Number.

Total synthesis of rhoiptelol B

Yadav,Pandurangam,Reddy, V. V. Bhadra,Reddy, B. V. Subba

experimental part, p. 4300 - 4306 (2011/02/25)

A simple and efficient total synthesis of rhoiptelol B, isolated from the the leaves and fruits of Rhoiptelea chiliantha, is achieved using Sharpless asymmetric epoxidation, 1,3-anti-chiral allylation, olefin cross-metathesis, Sharpless asymmetric dihydroxylation, and ferric chloride catalyzed intramolecular SN2 cyclization as the key steps
