Check Digit Verification of cas no
The CAS Registry Mumber 97997-08-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,9,9 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 97997-08:
(7*9)+(6*7)+(5*9)+(4*9)+(3*7)+(2*0)+(1*8)=215
215 % 10 = 5
So 97997-08-5 is a valid CAS Registry Number.

A General Method for the Preparation of γ-Substituted Cyclohexenals and Cycloheptenals
Jones, Tood K.,Denmark, Scott E.
, p. 4037 - 4045 (2007/10/02)
A general procedure for the preparation of γ-substituted or β'-unsaturated cycloalkenals is described.Starting from 2-cycloalkenones substituents may be introduced as nucleophiles by 1,4-addition followed by trapping of the regiospecifically generated enolate (86-92percent).Peracid oxidation of the enol silane derivative produces an α-hydroxy ketone which, after protection (70-93percent), is homologated to an enol ether by a Horner-Wittig reaction.Mild hydrolysis of the labile vinylogous acetal produces the aldehydes in good yields (62-75percent).Advantages of this method in comparison to known procedures are discussed as are other unsuccessful approaches to this substitution pattern.
