Check Digit Verification of cas no

The CAS Registry Mumber 22938-45-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,3 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 22938-45:
(7*2)+(6*2)+(5*9)+(4*3)+(3*8)+(2*4)+(1*5)=120
120 % 10 = 0
So 22938-45-0 is a valid CAS Registry Number.

IMINATION OF SULFUR-CONTAINING COMPOUNDS. XXIV. EFFECT OF THE ACIDIC CHARACTERISTICS OF THIOLS ON THE IMINATION OF SODIUM THIOLATES BY DICHLOROSULFONAMIDES

Koval', I. V.,Tarasenko, A. I.,Kremlev, M. M.

, p. 362 - 367 (2007/10/02)

The ability of sodium thiolates to be iminated by dichlorosulfonamides is due to a series of factors and primarily to the acidic characteristics of the initial thiols.The sodium salts of thiols with pKa > 8 are iminated comparatively readily by dichlorosulfonamides.Decrease in the pKa values of the thiols to 5-7 leads to a decrease in the imination rate and in the yields of the respective N,N'-bis(arylsulfonyl)sulfinamidines.The sodium salts of thiols with pKa 5 are not iminated by dichlorosulfonamides.Investigation of the acidic characteristics of the N,N'-bis(arylsulfonyl)sulfinamidines showed that substituents in the sulfinamidine fragment of the molecule make a larger contribution to the change in the acidic characteristics of the compounds than substituents in the arenesulfonyl fragment.
