Check Digit Verification of cas no

The CAS Registry Mumber 347386-51-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,7,3,8 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 347386-51:
(8*3)+(7*4)+(6*7)+(5*3)+(4*8)+(3*6)+(2*5)+(1*1)=170
170 % 10 = 0
So 347386-51-0 is a valid CAS Registry Number.

Chemical conversion of cyclic α-amino acids to cyclic α-aminophosphonic acids

Kaname,Mashige,Yoshifuji

, p. 531 - 536 (2007/10/03)

The oxidative decarboxylation of cyclic α-amino acids having urethane-type N-protecting groups with lead tetraacetate [Pb(OAc)4] gave 2-hydroxy derivatives, which were transformed into the corresponding α-aminophosphonic acid esters by treatment of trialkyl phosphites in the presence of Lewis acids. Deprotection and ester cleavage of the products in the usual manner afforded cyclic α-aminophosphonic acids. The convenient chemical conversion of five- and six-membered cyclic α-amino acids to the corresponding cyclic α-aminophosphonic acids has been accomplished.
