13247-98-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13247-98-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,4 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13247-98:
(7*1)+(6*3)+(5*2)+(4*4)+(3*7)+(2*9)+(1*8)=98
98 % 10 = 8
So 13247-98-8 is a valid CAS Registry Number.

A new synthesis of thiophosphoric acid esters with a C-S-P bond
Muller,Roth
, p. 501 - 502 (1990)
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.
