Check Digit Verification of cas no

The CAS Registry Mumber 134938-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,3 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 134938-40:
(8*1)+(7*3)+(6*4)+(5*9)+(4*3)+(3*8)+(2*4)+(1*0)=142
142 % 10 = 2
So 134938-40-2 is a valid CAS Registry Number.

Preparation, molecular structure, and diels-alder cycloaddition chemistry of β-functionalized alkynyl(phenyl)iodonium salts

Williamson, Bobby L.,Stang, Peter J.,Arif, Atta M.

, p. 2590 - 2595 (2007/10/02)

A variety of functionalized alkynytiodonium salts 4a-o are prepared in good yields via a novel iodonium-transfer process between the appropriate alkynylstannanes 2 and PhI+CN·-OTf. The electron-deficient acetylenes 4 readily undergo cycloadditi
