175347-80-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 175347-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,3,4 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 175347-80:
(8*1)+(7*7)+(6*5)+(5*3)+(4*4)+(3*7)+(2*8)+(1*0)=155
155 % 10 = 5
So 175347-80-5 is a valid CAS Registry Number.

Aprotic chloride and bromide-promoted alkyne-iminium ion cyclizations
Murata, Yoshinori,Overman, Larry E.
, p. 549 - 552 (2007/10/03)
The title cyclizations of 4-alkynyl- and 3-alkynyl-W-(methoxymethyl)-amines occur under milder conditions, and in the case of chloride in higher yields, than direct cyclizations of the corresponding secondary amine with formaldehyde and a halide salt.
