Check Digit Verification of cas no

The CAS Registry Mumber 59191-42-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,1,9 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 59191-42:
(7*5)+(6*9)+(5*1)+(4*9)+(3*1)+(2*4)+(1*2)=143
143 % 10 = 3
So 59191-42-3 is a valid CAS Registry Number.

An Amidoalkylation of Trivalent Phosphorus Compounds with P(O)H Functions Including Acetic Acid Solutions of PCl3, RPCl2 or R2PCl, Diesters of Phosphorous Acid and Phosphorus-III-Acids

Oleksyszyn, Jozef

, p. 19 - 28 (2007/10/02)

An amidoalkylation of PCl3 or its organic derivatives in acetic acid solution takes place because equilibrium between AcOH and >P-Cl exist, leading to hydroxychlorophosphines.Those last compounds undergo an amidoalkylation like other nucleophiles.Based on these data, it was shown that an amidoalkylation reaction is usual for all phosphorus compounds with the R2P(O)H system and provides derivatives with the >N-C-P(O)R2 functions.The scope and limitation of these reactions are discussed.
