Check Digit Verification of cas no

The CAS Registry Mumber 63554-93-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,5,5 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 63554-93:
(7*6)+(6*3)+(5*5)+(4*5)+(3*4)+(2*9)+(1*3)=138
138 % 10 = 8
So 63554-93-8 is a valid CAS Registry Number.

Phosphorylation of alcohols with N-phosphoryl oxazolidinones employing copper(II) triflate catalysis

Jones, Simon,Smanmoo, Chaiwat

, p. 3271 - 3274 (2005)

(Chemical Equation Presented) Phosphoryl transfer from N-phosphoryl 5,5-diphenyl oxazolidinone is efficiently catalyzed by copper(II) triflate. The utility of this method has been demonstrated in the phosphorylation of representative primary, secondary, tertiary, phenolic, and allylic alcohols. These reaction conditions are significantly milder than employing alkoxides and allow the phosphorylation of biologically relevant molecules.
