Check Digit Verification of cas no

The CAS Registry Mumber 42331-00-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,3,3 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 42331-00:
(7*4)+(6*2)+(5*3)+(4*3)+(3*1)+(2*0)+(1*0)=70
70 % 10 = 0
So 42331-00-0 is a valid CAS Registry Number.

Chlorination/cyclodehydration of amino alcohols with SOCl2: An old reaction revisited

Xu, Feng,Simmons, Bryon,Reamer, Robert A.,Corley, Edward,Murry, Jerry,Tschaen, David

, p. 312 - 315 (2008/09/17)

(Chemical Equation Presented) A simple, one-pot preparation of cyclic amines via efficient chlorination of amino alcohols with use of SOCl2 has been developed. This approach obviates the need for the classical N-protection/O-activation/cyclization/deprotection sequence commonly employed for this type of transformation. The reaction pathways and the general scope of this method have also been investigated.
