Check Digit Verification of cas no

The CAS Registry Mumber 226546-08-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,6,5,4 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 226546-08:
(8*2)+(7*2)+(6*6)+(5*5)+(4*4)+(3*6)+(2*0)+(1*8)=133
133 % 10 = 3
So 226546-08-3 is a valid CAS Registry Number.

An asymmetric route to novel chiral cyclohexenones with spiro-connected cyclopentenes. Further utility of chiral bicyclic thiolactams and the [3,3] thio-Claisen products

Lemieux,Devine,Mechelke,Meyers

, p. 3585 - 3591 (2007/10/03)

Sequential allylation of chiral, nonracemic thiolactam 8 affords clean thio-Claisen [3,3] products 11. The stereoselectivity of the rearrangement was found to be on the order of 10-11:1, with the exo-endo products responsible for the mixture. Addition of hydride or methyllithium-cerium chloride gave clean addition to the thiolactam in the form of its iminium salts 12. Hydrolysis gave 4,4-dialkylcyclohexenones 15, which were cyclized to the cyclopentene derivatives 16 using Grubbs' catalyst.
