13344-04-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13344-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,4 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13344-04:
(7*1)+(6*3)+(5*3)+(4*4)+(3*4)+(2*0)+(1*4)=72
72 % 10 = 2
So 13344-04-2 is a valid CAS Registry Number.

New synthesis of unsymmetrical dithia compounds
Smith, Keith,Tzimas, Michael
, p. 2381 - 2382 (2007/10/02)
1,2-Dithiacycloalkanes undergo nucleophilic ring-opening with organolithium reagents; the intermediates can be treated with electrophiles to provide unsymmetrical dithia compounds in high yields.
