Check Digit Verification of cas no

The CAS Registry Mumber 1228532-17-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,5,3 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1228532-17:
(9*1)+(8*2)+(7*2)+(6*8)+(5*5)+(4*3)+(3*2)+(2*1)+(1*7)=139
139 % 10 = 9
So 1228532-17-9 is a valid CAS Registry Number.

Synthesis of water-soluble phosphinophenol for traceless staudinger ligation

Weisbrod, Samuel H.,Marx, Andreas

, p. 787 - 789 (2010)

The traceless Staudinger ligation can be mediated in water without organic co-solvents if charged groups render the phenylphosphine reagent water soluble. Here the synthesis of a new water-soluble phosphine is presented based on a diphenylphosphino-phenol reagent. Staudinger ligation with this reagent and azido glycine amide showed conversion of 77%.
