1268357-03-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1268357-03-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,3,5 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1268357-03:
(9*1)+(8*2)+(7*6)+(6*8)+(5*3)+(4*5)+(3*7)+(2*0)+(1*3)=174
174 % 10 = 4
So 1268357-03-4 is a valid CAS Registry Number.

Synthesis and applications of sulfur-substituted cis-hexahydro-2- quinolinones
Chou, Shang-Shing P.,Cai, Yi-Lin
, p. 1183 - 1186 (2011)
An efficient synthesis of sulfur-substituted cis-hexahydro-2-quinolinones has been achieved by an aza-Diels-Alder reaction of p-toluenesulfonyl isocyanate with a diene precursor derived from a bicyclic 3-sulfolene via ring-closing metathesis. S
