Check Digit Verification of cas no

The CAS Registry Mumber 56044-12-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,0,4 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 56044-12:
103 % 10 = 3
So 56044-12-3 is a valid CAS Registry Number.

Quinazolines 1. Synthesis and chemical reactions of 6-chlorosulfonyl- quinazoline-2,4-diones


, p. 324 - 329 (2008)

Treatment of quinazoline-2,4-dione and its symmetrical 1,3-dialkyl derivatives with chlorosulfonic acid gave the corresponding 6- chlorosulfonylquinazoline-2,4-diones. Reaction of the compounds obtained with nucleophilic agents (water, ammonia, aliphatic and cyclic amines) gave the corresponding free 2,4-dioxoquinazoline-6-sulfonic acids, 6- sulfamidoquinazoline-2,4-diones, and 2,4-dioxoquinazoline-6-sulfonic acid amides.



Paragraph 00192; 00193; 00194, (2016/07/05)

The present invention relates to compounds of formula I that function as inhibitors of PARG (Poly ADP-ribose glycohydrolase) enzyme activity wherein R1a, R1b, R1c, R1d, R1e, W, X1, X2, X3, X4, X5, X6, X7, c are each as defined herein. The present invention also relates to processes for the preparation of these compounds, to pharmaceutical compositions comprising them, and to their use in the treatment of proliferative disorders, such as cancer, as well as other diseases or conditions in which PARG activity is implicated.
