Check Digit Verification of cas no
The CAS Registry Mumber 6618-09-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,1 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6618-09:
(6*6)+(5*6)+(4*1)+(3*8)+(2*0)+(1*9)=103
103 % 10 = 3
So 6618-09-3 is a valid CAS Registry Number.

Trifluoropropynyl derivatives. I. Their preparation and reaction with difluorocarbene
Cullen,Leeder
, p. 1004 - 1008 (1966)
The trifluoropropynyl derivatives (CH3)2AsC≡CCF3, CH3As(C≡CCF3)2, (CH3)3SiC≡CCF3, and (C2H5)3GeC≡CCF3 can be prepared from CF3C≡CMgI and the appropriate organometallic halide. They react with CF2 [from (CH3)3SnCF3] yielding the novel cyclopropenyl derivatives RnMC=C(CF3)CF2 [RnM = (CH3)2As, (CH3)3Si, or (C2H5)3Ge]. (CH3)2- AsC≡CCF3 is also obtained by the reaction of CF3C≡CH with compounds with As-N, As-S, As-As, and As-O bonds. CF3CH≡CH and ClAs(CH3)2 afford a little (CH3)2AsC≡CCF3, but the main products are the isomers of the 1:1 adduct (CH3)2AsC(CF3)=CHCl.
