Check Digit Verification of cas no

The CAS Registry Mumber 949581-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,9,5,8 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 949581-32:
(8*9)+(7*4)+(6*9)+(5*5)+(4*8)+(3*1)+(2*3)+(1*2)=222
222 % 10 = 2
So 949581-32-2 is a valid CAS Registry Number.

A stereoselective route to multi-substituted tetrahydropyrans by vinyl radical cyclization

Hiramatsu, Naoki,Takahashi, Natsuko,Noyori, Ryoji,Mori, Yuji

, p. 8589 - 8597 (2007/10/03)

The tin-mediated 6-exo-trig radical cyclization of the acetylenic β-alkoxy acrylates proceeded smoothly to give fully substituted tetrahydropyrans in good yields with high equatorial selectivity irrespective of the stereochemistry of the propargylic posit
