Check Digit Verification of cas no

The CAS Registry Mumber 191612-46-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,6,1 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 191612-46:
(8*1)+(7*9)+(6*1)+(5*6)+(4*1)+(3*2)+(2*4)+(1*6)=131
131 % 10 = 1
So 191612-46-1 is a valid CAS Registry Number.

First total synthesis of (+)-Membrine

Wirth, Thomas

, p. 1155 - 1158 (1997)

The easily accessible, optically active diselenide 1 is converted into the chiral selenium electrophile 2 and used for oxyselenenylation reactions of alkenes with functionalized nucleophiles. This reaction allows the synthesis of addition products 4, 6 and 10 with the selenium functionality as precursors for an intramolecular radical cyclization. This strategy is applied to the first total synthesis of optically pure (+)-membrine (13) by a short synthetic sequence. VCH Verlagsgesellschaft mbH, 1997.
