Check Digit Verification of cas no

The CAS Registry Mumber 99233-30-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,3 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99233-30:
(7*9)+(6*9)+(5*2)+(4*3)+(3*3)+(2*3)+(1*0)=154
154 % 10 = 4
So 99233-30-4 is a valid CAS Registry Number.

Logical design and synthesis of indole-2,3-diones and 2-hydroxy-3(2H)- benzofuranones via one-pot intramolecular cyclization

Gao, Fang-Fang,Xue, Wei-Jian,Wang, Jun-Gang,Wu, An-Xin

supporting information, p. 4331 - 4335 (2014/06/10)

A novel and attractive protocol to synthesis indole-2,3-diones and 2-hydroxy-3(2H)-benzofuranones and via copper(II) oxide catalyzed intramolecular cyclization is described. This method possesses functional-group compatibility, easy workup procedure, shorter reaction time and high yields.
