Check Digit Verification of cas no

The CAS Registry Mumber 128164-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,1,6 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128164-69:
(8*1)+(7*2)+(6*8)+(5*1)+(4*6)+(3*4)+(2*6)+(1*9)=132
132 % 10 = 2
So 128164-69-2 is a valid CAS Registry Number.

Rearrangements of Bridgehead Bromides. A Direct Synthesis of epi-Modhephene

Kraus, George A.,Shi, Jianmin

, p. 5423 - 5424 (1990)

The reaction of nucleophiles with bridgehead bromides 3 and 4 affords rearrangement products resulting from addition of the nucleophile to the carbonyl group followed by ring contraction.This rearrangement has been employed in a direct synthesis of epi-mo

Reactions of Bridgehead Halides. A Synthesis of Modhephene, Isomodhephene, and epi-Modhephene

Kraus, George A.,Shi, Jianmin

, p. 4147 - 4151 (2007/10/02)

A synthesis of modhephene has been achieved, the key feature of which is the use of a novel nucleophilic addition/rearrangement reaction to develop the carbon framework.Stereochemical control of the stereogenic center bearing the methyl group was accompli
