10448-51-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 10448-51-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,4 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 10448-51:
(7*1)+(6*0)+(5*4)+(4*4)+(3*8)+(2*5)+(1*1)=78
78 % 10 = 8
So 10448-51-8 is a valid CAS Registry Number.

Mass spectrometric degradation reactions of steroids with hydroxy groups in positions 12 and 17β depend on the configuration of the C-12 hydroxy group. In compounds with a 12α-hydroxy group, this group and the hydrogen in position 17α is eliminated as H2O. This reaction is followed by loss of a methyl radical. In the isomers with a 12β-hydroxy group this reaction is not possible. Here the loss of carbon 15-17 dominates the production of an ion by loss of two molecules of water. Key ions of mass 97 as well as M-44 and M-74 ions are produced by 17 keto steroids with a hydroxy group in position 12. If the rings A and B are cis-connected less specific degradation reactions are observed.
