Check Digit Verification of cas no
The CAS Registry Mumber 39834-32-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,8,3 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 39834-32:
(7*3)+(6*9)+(5*8)+(4*3)+(3*4)+(2*3)+(1*2)=147
147 % 10 = 7
So 39834-32-7 is a valid CAS Registry Number.

EXPLORATORY STUDY ON α-METALLO SELENONES : Original Syntheses of Oxaspiropentanes.
Krief, A.,Dumont W.,Laboureur, J.L.
, p. 3265 - 3268 (2007/10/02)
Oxaspiropentanes have been obtained from α-metallocyclopropyl phenyl selenones and carbonyl compounds and on reaction of a base with β-hydroxyalkyl cyclopropyl selenones.The original reactivity of other β-hydroxyalkyl selenones is also disclosed.
