Check Digit Verification of cas no

The CAS Registry Mumber 63539-64-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,5,3 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 63539-64:
(7*6)+(6*3)+(5*5)+(4*3)+(3*9)+(2*6)+(1*4)=140
140 % 10 = 0
So 63539-64-0 is a valid CAS Registry Number.

Investigation of the thionation reaction of cyclic imides

Orzeszko,Maurin,Melon-Ksyta

, p. 1035 - 1040 (2007/10/03)

A series of monothioimides and dithioimides were synthesised using Lawesson's reagent. It has been found that two main effects affect thionation reaction. The high polarity of carbonyl groups leads to good yields of mono- and dithioimides. On the other hand, steric hindrance in the vicinity of the carbonyl group strongly inhibits the replacement of the oxygen atom by sulfur.
