Check Digit Verification of cas no

The CAS Registry Mumber 32773-29-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,7,7 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 32773-29:
(7*3)+(6*2)+(5*7)+(4*7)+(3*3)+(2*2)+(1*9)=118
118 % 10 = 8
So 32773-29-8 is a valid CAS Registry Number.

Synthesis and application of isocyanates radiolabeled with carbon-11

Wilson, Alan A.,Garcia, Armando,Houle, Sylvain,Sadovski, Oleg,Vasdev, Neil

supporting information; experimental part, p. 259 - 264 (2011/03/19)

Carbon-11 labeled isocyanates are efficiently prepared by dehydration of [11C]carbamate salts, which in turn are easily formed from cyclotron-produced [11C]CO2 and amines in the presence of a CO2 fixation agent. The [11C]isocyanates are useful radiosynthons for the synthesis of a variety of [carbonyl-11C]- labeled asymmetrical ureas and carbamate esters. The method is well suited to incorporate any isotope of carbon, and is especially useful for positron emission tomography (PET) radiotracers for in vivo imaging. This is demonstrated by using the method to make [carbonyl-11C]-6-hydroxy-[1,1′- biphenyl]-3-yl cyclohexylcarbamate which is a novel radiotracer for PET imaging of fatty acid amide hydrolase.
