Check Digit Verification of cas no
The CAS Registry Mumber 1659-68-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1659-68:
(6*1)+(5*6)+(4*5)+(3*9)+(2*6)+(1*8)=103
103 % 10 = 3
So 1659-68-3 is a valid CAS Registry Number.

Organometallic Compounds in Organic Synthesis. Part 14. Tricarbonyliron as Lateral Control Group in the Selective Alkaline Hydrolysis of some Cyclohexa-1,3-diene Carboxylic Esters
Bandara, B. M. Ratnayake,Birch, Arthur J.,Raverty, Warwick D.
, p. 1763 - 1770 (2007/10/02)
Alkaline hydrolyses of a number of methoxycarbonyl derivatives of cyclohexa-1,3-diene-Fe(CO)3 have been used as indices of steric and electronic effects on reactivities of the ester groups.A β-CO2Me or a 1-CO2Me group is resistant to hydrolysis for steric
