Check Digit Verification of cas no
The CAS Registry Mumber 112481-21-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,4,8 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 112481-21:
(8*1)+(7*1)+(6*2)+(5*4)+(4*8)+(3*1)+(2*2)+(1*1)=87
87 % 10 = 7
So 112481-21-7 is a valid CAS Registry Number.

Amino Acids, 18. - Preparation and Reactions of 2-Isocyanato-2-alkenoates
Effenberger, Franz,Kuehlwein, Juergen,Baumgartner, Christian
, p. 1069 - 1074 (2007/10/02)
2-Isocyanato-2-alkenoates 3 were obtained in good yields by the perrhenate-catalyzed decomposition of 2-azidoalkanoates 1 in the presence of diphosgene (2a) or phosgene (2b).Methyl 2-azidopropionate (1h) reacts to give a mixture of methyl 2-isocyanato-2-p
