Check Digit Verification of cas no

The CAS Registry Mumber 1335200-83-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,2,0 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1335200-83:
(9*1)+(8*3)+(7*3)+(6*5)+(5*2)+(4*0)+(3*0)+(2*8)+(1*3)=113
113 % 10 = 3
So 1335200-83-3 is a valid CAS Registry Number.

An improved stereoselective total synthesis of (R)-rugulactone

Goswami, Abhishek,Saikia, Partha Pratim,Saikia, Bishwajit,Chaturvedi, Devdutt,Barua, Nabin C.

, p. 5133 - 5135 (2011)

A novel route for the stereoselective total synthesis of (R)-rugulactone 1 has been developed, starting from substituted epoxide 4 and 3- phenylpropionaldehyde 5 employing Julia-Kocienski olefination as a key step to construct E-configured α,β-unsaturated keto-group. The overall yield of the synthesized rugulactone is 19.94% and is better than the reported methods.
