Check Digit Verification of cas no

The CAS Registry Mumber 1373037-72-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,0,3 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1373037-72:
(9*1)+(8*3)+(7*7)+(6*3)+(5*0)+(4*3)+(3*7)+(2*7)+(1*2)=149
149 % 10 = 9
So 1373037-72-9 is a valid CAS Registry Number.

Asymmetric radical addition of TEMPO to titanium enolates

Mabe, Phillip J.,Zakarian, Armen

supporting information, p. 516 - 519 (2014/04/03)

A mild method for a-hydroxylation of N-acyl oxazolidinones by asymmetric radical addition of the 2,2,6,6-tetramethylpiperidine N-oxy (TEMPO) radical to titanium enolates was developed. The high diastereoselectivity and broad scope of the reaction show synthetic utility for the a-hydroxylation of substrates that are not tolerant to strongly basic conditions.
