Check Digit Verification of cas no
The CAS Registry Mumber 51748-05-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,7,4 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 51748-05:
(7*5)+(6*1)+(5*7)+(4*4)+(3*8)+(2*0)+(1*5)=121
121 % 10 = 1
So 51748-05-1 is a valid CAS Registry Number.

Production of phosphoro chloride thiolates
-
, (2008/06/13)
A process for the production of a phosphoro chloride thiolate of the formula STR1 wherein R1 is alkyl, alkoxyalkyl, aryl, or aryl substituted by alkyl, alkoxy or halogen, and R2 is alkyl, comprising reacting a mixture of a dialkyl chlorophosphite of the formula and an alkyl dichloro-phosphite of the formula with a sulphenyl chloride of the formula to produce a mixture of a phosphorochloridothiolate of the formula STR2 and a phosphorodichloridothiolate of the formula STR3 and reacting the mixture without isolation with an alcohol of the formula in the presence of a dehydrochlorinating agent thereby to convert the phosphorodichloridothiolate of the formula STR4 to additional phosphorochloridothiolate STR5 The starting mixture is produced by reacting phosphorus trichloride with a trialkyl phosphite, or with an alcohol in the presence of a dehydrochlorinating agent.
