Check Digit Verification of cas no

The CAS Registry Mumber 1158806-05-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,8,8,0 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1158806-05:
(9*1)+(8*1)+(7*5)+(6*8)+(5*8)+(4*0)+(3*6)+(2*0)+(1*5)=163
163 % 10 = 3
So 1158806-05-3 is a valid CAS Registry Number.

Highly efficient synthesis of functionalized dihydronaphthalenes, tetrahydronaphthalenes, and tetrahydroisoquinolines by iron-catalyzed intramolecular Friedel-Crafts reaction of aryl-containing propargylic alcohols

Huang, Wen,Hong, Longcheng,Zheng, Pengzhi,Liu, Ruiting,Zhou, Xigeng

body text, p. 3603 - 3610 (2009/09/06)

An efficient, convenient, and one-pot procedure for the synthesis of a series of new dihydro- and tetrahydronaphthalenes as well as tetrahydroisoquinolines has been established through Lewis acid-catalyzed intramolecular Friedel-Crafts reaction of aryl-substituted propargylic alcohols.
