Check Digit Verification of cas no

The CAS Registry Mumber 1335406-48-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,4,0 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1335406-48:
(9*1)+(8*3)+(7*3)+(6*5)+(5*4)+(4*0)+(3*6)+(2*4)+(1*8)=138
138 % 10 = 8
So 1335406-48-8 is a valid CAS Registry Number.

Synthesis of deuterium-labeled d3-androstenone and d 3-skatole for boar taint analysis

Fischer, Jochen,Elsinghorst, Paul W.,Wuest, Matthias

, p. 591 - 596 (2011)

The steroidal pig pheromone androstenone (5α-androst-16-en-3-one) as well as the indole derivate skatole are known to be the major compounds contributing to boar taint. The preparation of 2H-labeled internal standards of androstenone and skatole for stable isotope dilution assay-gas chromatography-mass spectrometry analysis of pig back fat samples is presented. The synthesis of d3-androstenone is highlighted by a palladium catalyzed deuteration of a Δ5,6-double bond of a hydrophobic steroid in a polar, D2O-containing solvent mixture. Moreover, the utilization of D2O as a deuterium source with in situ formation of D2 by means of Mg0 was found to be a very feasible and convenient alternative with respect to costs and technical effort.
