Check Digit Verification of cas no

The CAS Registry Mumber 74810-56-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,1 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74810-56:
(7*7)+(6*4)+(5*8)+(4*1)+(3*0)+(2*5)+(1*6)=133
133 % 10 = 3
So 74810-56-3 is a valid CAS Registry Number.

Zur reaktion von organodichlorphosphinen mit 1,2-diolen

Richter, Wolf Jurgen

, p. 395 - 400 (2007/10/02)

The reaction of phosphorus dichlorides with aliphatic 1,2-diols is studied.The range of products varies strongly with the concentration of the base and the organic substituents.In addition to 1,2,3-dioxaphospholanes the corresponding 2-oxo-1,3,2-dioxaphospholanes and oxiphosphoranes are also formed.Using proper conditions the latter may become the dominant product.
