Check Digit Verification of cas no

The CAS Registry Mumber 502929-72-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,2,9,2 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 502929-72:
(8*5)+(7*0)+(6*2)+(5*9)+(4*2)+(3*9)+(2*7)+(1*2)=148
148 % 10 = 8
So 502929-72-8 is a valid CAS Registry Number.

AN EFFICIENT SYNTHESIS OF 1-AMINOPHOSPHONIC ACIDS AND ESTERS BEARING HETEROCYCLIC MOIETY

Boduszek, Bogdan

, p. 63 - 70 (2007/10/03)

New α-aminophosphonic esters and acids derived from furan, thiophene and pyrazole were prepared in high yield, in the reactions of benzylamine, benzhydrylamine or benzyl carbamate with heterocyclic aldehydes and diethyl or diphenyl phosphonates.The protecting groups at amine (benzyl or benzhydryl) were removed by hydrogenolysis or hydrolysis, respectively.The N-benzoyloxycarbonyl (Z-group) was removed by treatment with 45percent HBr in acetic acid. Key words: Diphenyl α-aminofurylmethyl phosphonate, α-aminothienylmethylphosphonic acid, α-aminopyrazolylmethylphosphonic acid, imines, benzyl carbamate.
