97231-82-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97231-82-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,2,3 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 97231-82:
(7*9)+(6*7)+(5*2)+(4*3)+(3*1)+(2*8)+(1*2)=148
148 % 10 = 8
So 97231-82-8 is a valid CAS Registry Number.

A SIMPLE SYNTHESIS OF α,β-UNSATURATED ALDEHYDES BY 1,3-CARBONYL TRANSPOSITION THROUGH ONE CARBON HOMOLOGATION
Dasgupta, Ratna,Ghatak, Usha Ranjan
, p. 1581 - 1584 (1985)
α,β-Unsaturated aldehydes are conveniently prepared from ketones through their β-diethoxymethyl derivatives by sodium borohydride reduction followed by acid-catalysed rearrangement of the resulting diacetal carbinols.
