Check Digit Verification of cas no

The CAS Registry Mumber 64757-32-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,7,5 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 64757-32:
(7*6)+(6*4)+(5*7)+(4*5)+(3*7)+(2*3)+(1*2)=150
150 % 10 = 0
So 64757-32-0 is a valid CAS Registry Number.

Process for preparing thiophene derivatives and thiophene derivatives obtained thereby

-

, (2008/06/13)

Process for the preparation of a series of thiophene derivatives, from which 2-thiopheneacetic acid derivatives can easily be prepared, in high yields and selectivity by using substituted or unsubstituted thiophenes as the starting materials by easy operations. 2-Thiopheneacetic acid derivatives are very useful compounds as the chemical modifier of penicillin and cephalosporin. Novel compounds, i.e. α-arylthio-2-thiopheneacetic acids are also disclosed. These compounds are useful as the intermediates of the synthesis of 2-thiopheneacetic acids.

Cephalosporins having a sulfur containing functional group in the 7-position side chain

-

, (2008/06/13)

Cephalosporins having a sulfur-containing functional group of the formula STR1 present at the carbon atom directly bonded to the thienyl or furyl group in the side chain of the 7-position of cephem derivatives. These compounds are useful as anti-bacterial agents against Gram-positive and Gram-negative bacteria.
