Check Digit Verification of cas no

The CAS Registry Mumber 57287-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,2,8 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 57287-75:
(7*5)+(6*7)+(5*2)+(4*8)+(3*7)+(2*7)+(1*5)=159
159 % 10 = 9
So 57287-75-9 is a valid CAS Registry Number.

Reaction of Tricoordinate Phosphorus Compounds with Organophosphorus Pseudohalogens. 1. Desulfurization and Deoxygenation of Oxophosphoranesulfenyl Chlorides. Scope and Mechanism

Krawczyk, E.,Mikolajczak, J.,Skowronska, A.,Michalski, J.

, p. 4963 - 4970 (1992)

The reaction of oxophosphoranesulfenyl chlorides RR'P(O)SCl 2 with PIII compounds has been investigated.Its mechanistic features have been elucidated by variable-temperature 31P NMR spectroscopy and stereochemical changes at PIV and PIII phosphorus centers.These studies show that in all cases phosphonium intermediates containing the sulfur bridge >P(O)-S-P(+)P(S)-O-P(+)-Cl(-).The latter decomposes by the attack of the chloride anion on the thiophosphoryl center (deoxygenation pathway). 31P NMR studies fully corroborated the observed stereochemical changes.
