The CAS Registry Mumber 127019-55-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,1 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 127019-55:
(8*1)+(7*2)+(6*7)+(5*0)+(4*1)+(3*9)+(2*5)+(1*5)=110
110 % 10 = 0
So 127019-55-0 is a valid CAS Registry Number.

Conversion of Thiobiurets to Thiadiazolones and Triazinones by Oxidative Cyclization
Shaban, M. E.,Guirguis, D. B.,Gad, E. S.
, p. 147 - 164 (2007/10/03)
1-Aroyl-5-aryl-2-thiobiurets (2a-i) react with hydrogen peroxide in an acidic medium yielding the new 5-aroylamino-2-aryl-2H-1,2,4-thiadiazol-3-ones (3a-i). On treatment with alkali, thiobiurets (2a-c) gave 6-aryl-1,2,3,4-tetrahydro-1,3,5-triazin-2-ones (
