Check Digit Verification of cas no
The CAS Registry Mumber 21089-13-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,8 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21089-13:
(7*2)+(6*1)+(5*0)+(4*8)+(3*9)+(2*1)+(1*3)=84
84 % 10 = 4
So 21089-13-4 is a valid CAS Registry Number.

, p. 1147 - 1155 (2013/09/23)
We investigated the mechanism of the reaction of paraformaldehyde with phosphorus trichloride in the presence of carboxylic acids (acetic, propanoic, and formic). Our results revealed that bisphosphonic acids were obtained without the use of water. The structures of the reaction products were studied by 1D and 2D homonuclear and heteronuclear 1H-, 13C-, 31P- NMR spectroscopy. [Supplementary materials are available for this article.
