Check Digit Verification of cas no

The CAS Registry Mumber 70244-13-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,4 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 70244-13:
(7*7)+(6*0)+(5*2)+(4*4)+(3*4)+(2*1)+(1*3)=92
92 % 10 = 2
So 70244-13-2 is a valid CAS Registry Number.

The mass spectra of diethylstilbestrol and related compounds

Engel,Marshall,Orr,Reinhold,Carter

, p. 582 - 586 (1978)

The low resolution mass spectra of E-3,4-bis-(p-hydroxyphenyl)-hex-3-ene (diethylstilbestrol), E-[1,1,1-3H3]3,4-bis-(p-hydroxyphenyl)-hex-3-ene, E-2,3-bis-(p-hydroxyphenyl)-but-2-ene (dimethylstilbestrol), E,E-3,4-bis-(p-hydroxyphenyl)hexa-2,4-diene (dienestrol) and 3,4-bis-(p- hydroxyphenyl)-hexane (hexestrol) were examined as the parent compounds, their diacetates, dimethyl ethers, and bis-trimethylsilyl ethers. In addition, the mass spectra of the diethyl ether and the hexadeuteriodimethyl ether of E-3,4-bis-(p-hydroxyphenyl)-hex-3-ene were studied. Each compound gives rise to several sets of characteristic fragment ions associated with loss of alkyl groups, loss of aryl groups and rearrangements. An ion of m/e 165 (C13H9) was found in the spectra of all the compounds studied. With the aid of high resolution mass spectrometry empirical formulae were assigned to major ions of the free diphenols.
