Check Digit Verification of cas no
The CAS Registry Mumber 194423-47-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,4,2 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 194423-47:
(8*1)+(7*9)+(6*4)+(5*4)+(4*2)+(3*3)+(2*4)+(1*7)=147
147 % 10 = 7
So 194423-47-7 is a valid CAS Registry Number.

Synthesis of polydeuterated benzothiazoles via supercritical deuteration of anilines
Junk, Thomas,Catallo, W. James,Civils, L. Dana
, p. 625 - 630 (2007/10/03)
2-[2H]Benzothiazole, readily available according to the literature, was observed to undergo slow isotope exchange in water. This necessitated development of practical syntheses for benzothiazoles carrying deuterium labels in positions other than 2. [4,5,6,7-2H4]Benzothiazole and 4-[2H3]methyl[5,6,7-2H3]benzothiazole were prepared in good yields from [2H7]aniline and 2-[2H9]toluidine, which were obtained by novel rapid isotope exchange in supercritical deuterium oxide.
