172507-08-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172507-08-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,5,0 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 172507-08:
(8*1)+(7*7)+(6*2)+(5*5)+(4*0)+(3*7)+(2*0)+(1*8)=123
123 % 10 = 3
So 172507-08-3 is a valid CAS Registry Number.

Synthetic Routes to 1,4-Difunctionalized Cycloheptenes
Maier, Martin E.,Langenbacher, Diane,Rebien, Frank
, p. 1843 - 1848 (2007/10/03)
Two routes to 1,4-difunctionalized cycloheptenes are described.The first one is based on a fluoride-induced fragmentation reaction of the bicyclic heptanesilyl monosulfate 10.This compound in turn was prepared by a ketene-cyclopentene cycloaddition
