Check Digit Verification of cas no

The CAS Registry Mumber 1353040-07-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,3,0,4 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1353040-07:
(9*1)+(8*3)+(7*5)+(6*3)+(5*0)+(4*4)+(3*0)+(2*0)+(1*7)=109
109 % 10 = 9
So 1353040-07-9 is a valid CAS Registry Number.

Copper(II)-mediated intramolecular cyclization of (Z)-chalcogenoenynes: Synthesis of 3-halochalcogenophene derivatives

Barancelli, Daniela A.,Schumacher, Ricardo F.,Leite, Marlon R.,Zeni, Gilson

, p. 6713 - 6718 (2011)

We present our results on the cyclization of (Z)-chalcogenoenynes mediated by copper(II) salts to afford 3-halochalcogenophenes in satisfactory yields through an intramolecular 5-endo-dig cyclization. The methodology was carried out using CuCl2
