128371-61-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128371-61-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,3,7 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128371-61:
(8*1)+(7*2)+(6*8)+(5*3)+(4*7)+(3*1)+(2*6)+(1*1)=129
129 % 10 = 9
So 128371-61-9 is a valid CAS Registry Number.

A new synthesis of thiophosphoric acid esters with a C-S-P bond
Muller,Roth
, p. 501 - 502 (2007/10/02)
Various S-substituted thiosuccinimides 1a-d and thiophthalimides 2a-d were found to react with trialkylphosphites according to a Michaelis-Arbuzov type mechanism. This provides an efficient way to prepare thiophosphoric acid esters, particularly thiophospholipids, with a C-S-P bond.
