Check Digit Verification of cas no

The CAS Registry Mumber 388620-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,8,6,2 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 388620-99:
(8*3)+(7*8)+(6*8)+(5*6)+(4*2)+(3*0)+(2*9)+(1*9)=193
193 % 10 = 3
So 388620-99-3 is a valid CAS Registry Number.

The synthesis and acid-catalyzed hydrolysis of N-(4-substitutedphenyl)-O- benzenedisulfonimides

Bekdemir, Yunus,Eren, Bilge,Kuetuek, Halil

experimental part, p. 689 - 696 (2012/07/17)

The acid catalyzed hydrolyses of some cyclic disulfonimides, N-(4-substitutedphenyl)-o-benzenedisulfonimides (1a-d) have been studied in concentrated aqueous acidic solutions. Analysis of the data by the Excess Acidity Method, activation parameters, substituent, and solvent deuterium isotope effect are all indicate hydrolysis by an A-1 mechanism in the studied range.
