56712-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56712-23-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,7,1 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 56712-23:
(7*5)+(6*6)+(5*7)+(4*1)+(3*2)+(2*2)+(1*3)=123
123 % 10 = 3
So 56712-23-3 is a valid CAS Registry Number.

Matrix isolation spectroscopy allows the direct identification of ylide 1 and its cyclic isomer 2. They were obtained by pyrolysis of 1,2,4-trithiolane under high vacuum; the cyclic compound forms from 1 by thermal ring closure in a kinetically controlled reaction.
