Check Digit Verification of cas no
The CAS Registry Mumber 67198-87-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,1,9 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 67198-87:
(7*6)+(6*7)+(5*1)+(4*9)+(3*8)+(2*8)+(1*7)=172
172 % 10 = 2
So 67198-87-2 is a valid CAS Registry Number.

, (2008/06/13)
Process for 4-(D-3-amino-3-carboxypropoxy)phenylglyoxylic acid oxime as an amino-protected ester comprising alkylating an amino-protected D-methionine silyl ester with an alkyl or benzyl iodide; cyclizing the alkylsulfonium iodide to an amino-protected D-homoserine lactone; hydrolyzing the lactone to an amino-protected D-homoserine in aqueous base; coupling, to form an ether, the amino-protected D-homoserine as an ester with an ester of 4-hydroxyphenylglyoxylic acid; and forming the oxime of the ether or alternatively coupling the D-homoserine ester with a protected-oxime of an esterified 4-hydroxyphenylglyoxylic acid. The product is useful in preparing the antibiotic FR 1923.
