Check Digit Verification of cas no
The CAS Registry Mumber 93951-99-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,9,5 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 93951-99:
(7*9)+(6*3)+(5*9)+(4*5)+(3*1)+(2*9)+(1*9)=176
176 % 10 = 6
So 93951-99-6 is a valid CAS Registry Number.

Synthesis of mixed halogenated trihalomethanes labelled with the stable isotopes 2H or 13C
Vermeulen,Sangaiah,Ball,Gold
, p. 835 - 843 (1995)
2H and 13C-labelled bromodichloromethane and chlorodibromomethane were obtained in yields of 20 and 12% (for 2H) and 6 and 3% (for 13C) respectively from a convenient aluminum chloride-catalyzed reaction of bromoethane with commercially-available isotopically-substituted chloroform. The products were purified by preparative gas chromatography and-characterized by MS and 13C NMR, and by 1H for the 13C-labelled material; mass and nuclear magnetic resonance spectroscopy data are reported.
