Check Digit Verification of cas no

The CAS Registry Mumber 182558-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,5,5 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 182558-04:
(8*1)+(7*8)+(6*2)+(5*5)+(4*5)+(3*8)+(2*0)+(1*4)=149
149 % 10 = 9
So 182558-04-9 is a valid CAS Registry Number.

Tocopherols by hydride reduction of dialkylamino derivatives

Netscher, Thomas,Mazzini, Francesco,Jestin, Roselyne

, p. 1176 - 1183 (2007)

Aminomethylation with Mannich reagents derived from secondary amines and paraformaldehyde under improved conditions has been used to convert non-α-tocopherol homologues into α-tocopherol, the biologically most important vitamin E compound. Mono- and bis(aminomethylated) β-, γ-and δ-tocopherol were then subsequently transformed into the corresponding tocopherols (α- and β-tocopherol) by reductive deamination. As an alternative to classical catalytic hydrogenation in the last step, efficient laboratory protocols using complex hydrides have been derived and applied to the preparation of labelled vitamin E compounds.
