Check Digit Verification of cas no
The CAS Registry Mumber 16452-32-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,4,5 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16452-32:
(7*1)+(6*6)+(5*4)+(4*5)+(3*2)+(2*3)+(1*2)=97
97 % 10 = 7
So 16452-32-7 is a valid CAS Registry Number.

Synthesis of (+/-)-Geosmin. Part 2. A One-Pot Four-Step Conversion of 1,4a-Dimethyl-1α,8aα-epoxyperhydronaphthalen-2-one into (+/-)-Geosmin
Hansson, Lars,Carlson, Rolf
, p. 1042 - 1045 (2007/10/02)
A one-pot four-step procedure for the conversion of 1,4a-dimethyl-1α,8aα-epoxyperhydronaphthalen-2-one into (+/-)-geosmin is presented.The synthesis was achieved by a reduction-derivatization-double reduction sequence, which afforded the title compound in 35percent overall yield from ethyl vinyl ketone.Some other possible to (+/-)-geosmin have been investigated.A high yield synthesis of the C-1 epimer of (+/-)-geosmin using the same epoxide as the starting material is also described.Comparision with other previously reported total syntheses of the title compound is presented.
