Check Digit Verification of cas no

The CAS Registry Mumber 144108-02-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,1,0 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 144108-02:
(8*1)+(7*4)+(6*4)+(5*1)+(4*0)+(3*8)+(2*0)+(1*2)=91
91 % 10 = 1
So 144108-02-1 is a valid CAS Registry Number.

An Improved Synthesis of Naphthoate Precursors to Olivin

Roush, William R.,Murphy, Megan

, p. 6622 - 6629 (1992)

An improved synthesis of olivin synthetic intermediate 3 is described.The synthesis involves the Horner-Wadsworth-Emmons coupling of 14 and 16, the diastereoselective vinylcuprate addition to enone 20, and the condensation of isocoumarin 25 and methyl acetate.A parallel sequence starting from allyl ether 26 has provided naphthoate 35 that is suitably differentiated for glycosylation studies.
