Check Digit Verification of cas no

The CAS Registry Mumber 58992-26-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,9,9 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 58992-26:
(7*5)+(6*8)+(5*9)+(4*9)+(3*2)+(2*2)+(1*6)=180
180 % 10 = 0
So 58992-26-0 is a valid CAS Registry Number.

1-Thio-Substituted Cyclopropylphosphonium Salts: Reagents for Pentannulation Reactions

Marino, Joseph P.,Ferro, Michael P.

, p. 1828 - 1832 (2007/10/02)

The preparation and pentannulation reactions of 1-(phenylthio)-, 1-(methylthio)- and 1-(isopropylthio)cyclopropylphosphonium fluoborates are described.As part of a synthetic approach to portulal, a plant-growth regulator, 2-(carbomethoxy)-4-methylcyclohept-4-en-1-one is converted to its bicyclodecenone derivative.This annulation reaction illustrates the synthetic application and limitations of the 1-thio-substituted cyclopropylphosphonium reagents.
