Check Digit Verification of cas no

The CAS Registry Mumber 91789-41-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,8 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91789-41:
(7*9)+(6*1)+(5*7)+(4*8)+(3*9)+(2*4)+(1*1)=172
172 % 10 = 2
So 91789-41-2 is a valid CAS Registry Number.

Synthesis of 2,5- and 2,6-Norbornane Derivatives with Prostaglandin-like Side Chains

Davies, David I.,Gomez, Peter M.,Hallett, Peter

, p. 843 - 848 (2007/10/02)

Norborn-5-en-2-endo-ylmethyl toluene-4-sulphonate, readily prepared from Diels-Alder adduct of cyclopentadiene and acrylic acid, has been converted, in six and seven stages respectively, into the prostaglandin-like compounds 2-endo-(6-carboxyhex-2-enyl)norbornan-5- and -6-exo-yl 2-hydroxyheptyl ethers.The synthesis of the former compounds involves a novel hydroxyethoxy mercuriation of a norbornene double bond.
