19236-48-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19236-48-7 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, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19236-48:
(7*1)+(6*9)+(5*2)+(4*3)+(3*6)+(2*4)+(1*8)=117
117 % 10 = 7
So 19236-48-7 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.
