Check Digit Verification of cas no

The CAS Registry Mumber 68206-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,2,0 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 68206-77:
(7*6)+(6*8)+(5*2)+(4*0)+(3*6)+(2*7)+(1*7)=139
139 % 10 = 9
So 68206-77-9 is a valid CAS Registry Number.

STUDIES ON ORGANOPHOSPHORUS COMPOUNDS PART 55 THE TRANSFORMATION OF NITRILES TO THIOAMIDES WITH O,O-DIALKYLDITHIOPHOSPHORIC ACID

Shabana, R.,Meyer, H.J.,Lawesson, S.-O.

, p. 297 - 306 (2007/10/02)

The reaction between nitriles and O,O-dialkyldithiophosphoric acid (2) under anhydrous conditions produces O,O-diethyl-N-thiobenzoylamidophosphate (5), contrary to literature.When water is present the same reaction gives the corresponding thioamides in reasonable to good yields.Mechanistic considerations and spectral data are presented for the products.
