106019-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 106019-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,0,1 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 106019-33:
(8*1)+(7*0)+(6*6)+(5*0)+(4*1)+(3*9)+(2*3)+(1*3)=84
84 % 10 = 4
So 106019-33-4 is a valid CAS Registry Number.

SYNTHESIS OF PHOSPHONIC MONOESTERS FROM PHOSPHONOUS ACIDS
Karanewsky, Donald S.,Badia, Michael C.
, p. 1751 - 1754 (2007/10/02)
Phosphonic monoesters are prepared in a two-step procedure by DCC-DMAP mediated esterification of phosphonous acids and oxidation of the resulting phosphonous monoester.
