Check Digit Verification of cas no
The CAS Registry Mumber 109-47-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 109-47:
(5*1)+(4*0)+(3*9)+(2*4)+(1*7)=47
47 % 10 = 7
So 109-47-7 is a valid CAS Registry Number.

New synthesis of phosphorous and phosphoric acid esters
Froneman,Modro
, p. 201 - 204 (2007/10/02)
Reaction of alcohols with dialkyl phosphites in the presence of titanium tetraalkoxides results in a displacement of both or one ester function(s) by the RO groups of the alcohol used. The mixed phosphites, (R3O)(R1O)P(O)H, prepared by this method can be used as substrates for the mixed phosphates, (R4O)(R3O)(R1O)PO.
