Check Digit Verification of cas no

The CAS Registry Mumber 1571900-61-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,1,9,0 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1571900-61:
(9*1)+(8*5)+(7*7)+(6*1)+(5*9)+(4*0)+(3*0)+(2*6)+(1*1)=162
162 % 10 = 2
So 1571900-61-2 is a valid CAS Registry Number.

Towards the diastereoselective synthesis of derivative of 11′-epi-brevipolide H

Kumaraswamy, Gullapalli,Jayaprakash, Neerasa,Rambabu, Dasa,Ganguly, Aniban,Banerjee, Rajkumar

, p. 1793 - 1803 (2014/03/21)

An efficient diastereoselective synthesis of brevipolide H derivative is described. The approach features the use of (i) catalytic asymmetric transfer hydrogenation, (ii) hydroxyl-directed cyclopropanation, and (iii) substrate-controlled catalytic epoxidation and ring-closing metathesis. Remarkably, in this convergent synthesis process, stereogenic centers were installed through catalytic reactions with high stereocontrol, which greatly facilitates the synthesis of stereo-divergent derivatives.
