19236-51-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19236-51-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,2,3 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19236-51:
(7*1)+(6*9)+(5*2)+(4*3)+(3*6)+(2*5)+(1*1)=112
112 % 10 = 2
So 19236-51-2 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.
