1314807-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1314807-57-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,4,8,0 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1314807-57:
(9*1)+(8*3)+(7*1)+(6*4)+(5*8)+(4*0)+(3*7)+(2*5)+(1*7)=142
142 % 10 = 2
So 1314807-57-2 is a valid CAS Registry Number.

Heterocycles via intramolecular platinum-catalyzed propargylic substitution
Liang, Qiren,De Brabander, Jef K.
, p. 5046 - 5053 (2011/08/06)
We report a Pt(II)-catalyzed cyclization of nucleophile-tethered propargylic acetates yielding substituted heterocycles containing multiple heteroatoms including morpholines, dioxanes, and sulfamates with high cis-selectivity.
