Check Digit Verification of cas no

The CAS Registry Mumber 1228009-94-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,0,0 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1228009-94:
(9*1)+(8*2)+(7*2)+(6*8)+(5*0)+(4*0)+(3*9)+(2*9)+(1*4)=136
136 % 10 = 6
So 1228009-94-6 is a valid CAS Registry Number.

Synthesis and reactions of 4-benzoyl-1,5-diaryl-1h-pyrazole-3-carbonyl chlorides with various semi- and thiosemicarbazides

Korkusuz, Elif,Yildirim, Ismail

experimental part, p. 472 - 476 (2010/06/19)

(Chemical Equation Presented) The 1H-pyrazole-3-carboxylic acids 2 were converted via reactions of their acid chlorides 3 with some semi- and thiosemicarbazide derivatives into the corresponding new phenylsemi- and thiosemicarbazides 4a-e, 6, 5-(pyrazol-3-yl)-4H-1,2,4-triazol-3-thiones 5a,b, and 2-(pyrazol-3-yl)-1,3,4-thiadiazol 7 derivatives, in good yields (45-97%, respectively). The reactions of 4a,c,e with Lawesson reagent lead to the products 6 and 7 formation. The structures of these newly synthesized compounds were determined. from the IR, 1H- and 13C-NMR spectroscopic data and elemental analyses.
