Check Digit Verification of cas no

The CAS Registry Mumber 1058239-64-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,8,2,3 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1058239-64:
(9*1)+(8*0)+(7*5)+(6*8)+(5*2)+(4*3)+(3*9)+(2*6)+(1*4)=157
157 % 10 = 7
So 1058239-64-7 is a valid CAS Registry Number.

Halolactonization of γ-acetylenic acids: systhesis of novel spiroisoindole halobutyrolactones

Rammah, Mohamed M.,Othman, Mohamed,Msaddek, Moncef,Rammah, Mohamed B.

experimental part, p. 1971 - 1981 (2009/04/06)

γ-Acetylenic carboxylic acids are cyclized to spirohalo butyrolactones, in the presence of NBS or NIS and K2CO3. The corresponding 5(E)-haloalkylidene-spirobutyrolactones were isolated in high yields, and this process constitutes an easy and efficient route to analogous structures of natural products of biological interest.
