Check Digit Verification of cas no

The CAS Registry Mumber 16239-26-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,3 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 16239-26:
(7*1)+(6*6)+(5*2)+(4*3)+(3*9)+(2*2)+(1*6)=102
102 % 10 = 2
So 16239-26-2 is a valid CAS Registry Number.

Synthesis and structure of aroylamidines and N-arylbenzamidines hydrochlorides

Kuvaeva,Fedorova,Zaitsev,Yakovlev,Zakharov,Semakova

experimental part, p. 209 - 213 (2012/06/01)

Aroylamidines can be obtained as salts in a reaction of the corresponding arylcarbonitriles with anhydrous ethanol in the presence of dry HCl followed by treating intermediate imidoesters with alcoholic solution of ammonia. N-Arylbenzamidines are obtained by reacting benzonitrile with arylamines in the presence of AlCl3. The structure of arylamines and the reaction conditions signifi cantly affect the yield of the target product, and sometimes the very possibility of its preparation. Pleiades Publishing, Ltd., 2012.

Reaction of Sulphuryl Chloride with Some Schiff Bases

Dhar, Durga N.,Gupta, Sudha R.

, p. 533 - 535 (2007/10/02)

The reaction of sulphuryl chloride with schiff bases has been studied.In each case, pure crystalline products have been isolated, and their structures elucidated on the basis of IR, PMR and mass spectral data.A plausible mechanism is advanced for the formation of observed products.
