Check Digit Verification of cas no

The CAS Registry Mumber 251901-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,9,0 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 251901-57:
(8*2)+(7*5)+(6*1)+(5*9)+(4*0)+(3*1)+(2*5)+(1*7)=122
122 % 10 = 2
So 251901-57-2 is a valid CAS Registry Number.

Synthesis of benzo[b][1,4]thiazepines by the reaction of 3-aryl-1-(3-coumarinyl)propen-1-ones with 2-aminothiophenol [1]

Levai, Albert,Jeko, Jozsef,Gondos, Timea,Simon, Andras,Toth, Gabor

, p. 1453 - 1458 (2008/09/18)

(Chemical Equation Presented) 3-(2-Aryl-2,3-dihydro-benzo[b][1,4]thiazepin- 4-yl)chromen-2-ones (2a, e, f) and (Z)-3-(2,3-dihydro-2-arylbenzo[b][1,4] thiazepin-4(5H)-ylidene)chroman-2-ones (3a-f) have been synthesized by the reaction of 3-aryl-1-(3-coumarinyl)propen-1-ones (1a-f) with 2-aminothiophenol in a hot mixture of toluene and acetic acid. Structures of all new compounds and their complete 1H and 13C assignments were achieved applying different one- and two-dimensional nmr experiments in combination with various spectroscopic techniques.
