128500-88-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128500-88-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,0 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 128500-88:
(8*1)+(7*2)+(6*8)+(5*5)+(4*0)+(3*0)+(2*8)+(1*8)=119
119 % 10 = 9
So 128500-88-9 is a valid CAS Registry Number.

Concurrent Configurational Modyfication in Conjugated Dienes; a New Pathway in the Isomerization of Alkadienes
Thyagarajan, B. S.,Chandler, Richard A.
, p. 328 - 330 (2007/10/02)
The hexa-2,4-diene derivative (2), obtained from 1,6-di(phenylsulfonyl)hexa-2,4-diyne (1), is shown to undergo simultaneous isomerisation at both double bonds, through an elimination-addition pathway.
