Check Digit Verification of cas no

The CAS Registry Mumber 1241045-81-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,1,0,4 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1241045-81:
(9*1)+(8*2)+(7*4)+(6*1)+(5*0)+(4*4)+(3*5)+(2*8)+(1*1)=107
107 % 10 = 7
So 1241045-81-7 is a valid CAS Registry Number.

Synthesis of labeled ambroxol and its major metabolites

Latli, Bachir,Hrapchak, Matt,Switek, Heinz-Karl,Retz, Daniel M.,Krishnamurthy, Dhileepkumar,Senanayake, Chris H.

experimental part, p. 15 - 23 (2010/04/26)

Ambroxol is a mucolytic agent used in the treatment of respiratory diseases. Herein, we report the synthesis of carbon-14-labeled ambroxol with the radioactive atom(s) either on the benzylic carbon or uniformly in the cyclohexyl ring with specific activities of 59 and 81 mCi/mmol, respectively. We also describe the preparation of deuterium-labeled ambroxol, its deuterium-labeled tetrahydroquinazoline metabolite (DHTQ), carbon-13-labeled 3,5-dibromoanthranilic acid metabolite, as well as an unlabeled O-glucuronide conjugate.
