Check Digit Verification of cas no

The CAS Registry Mumber 61552-23-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,5,5 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 61552-23:
(7*6)+(6*1)+(5*5)+(4*5)+(3*2)+(2*2)+(1*3)=106
106 % 10 = 6
So 61552-23-6 is a valid CAS Registry Number.

First synthesis of (8-2H3)-(all-rac)-δ-tocopherol

Mazzini, Francesco,Alpi, Emanuele,Salvadori, Piero,Netscher, Thomas

, p. 2840 - 2844 (2007/10/03)

Trideuterated tocopherols were needed to be used as internal standards for our study about simultaneous quantitative determination of tocopherols in foodstuffs by mass spectrometry. Whilst procedures for trideuterated α-tocopherol have been recently optimized, no method is reported as regards δ-tocopherol. Different synthetic approaches are discussed, as well as the first procedure for the synthesis of (8-2H3)-(all-rac)-δ-tocopherol. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
