Check Digit Verification of cas no

The CAS Registry Mumber 134540-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,5,4 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 134540-75:
(8*1)+(7*3)+(6*4)+(5*5)+(4*4)+(3*0)+(2*7)+(1*5)=113
113 % 10 = 3
So 134540-75-3 is a valid CAS Registry Number.

A NOVEL ONE-POT SYNTHESIS OF TRIFLUOROMETHYLATED β,γ-UNSATURATED ESTERS AND NITRILES

Shen, Yanchang,Xiang, Yuejun

, p. 349 - 355 (2007/10/02)

Trifluoromethylated β,γ-unsaturated esters and nitriles can be synthesized by reaction of organozinc compounds with fluorinated β-ketophosphonium salts.This novel reaction without isolation of intermediates provides a convenient synthesis of the title compounds which may be useful intermediates for the preparation of fluorinated biologically active compounds.
