α-(Tosyloximino)-phenylessigsaeure-aethylester, also known as α-(Tosyloxyimino)phenylacetic acid ethyl ester, is an organic compound with the chemical formula C15H17NO4S. It is a derivative of phenylacetic acid, featuring an ethyl ester group and a tosyloxyimino (tosyloxy-N-imino) functional group. α-(Tosyloximino)-phenylessigsaeure-aethylester is often used in organic synthesis, particularly in the preparation of various pharmaceuticals and other chemical compounds. The tosyloxyimino group serves as a protecting group for the imine functionality, which can be selectively removed under certain conditions to regenerate the imine. This property makes α-(Tosyloxyimino)phenylacetic acid ethyl ester a valuable intermediate in the synthesis of complex molecules where temporary protection of the imine group is necessary.

Check Digit Verification of cas no

The CAS Registry Mumber 17512-83-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,1 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 17512-83:
(7*1)+(6*7)+(5*5)+(4*1)+(3*2)+(2*8)+(1*3)=103
103 % 10 = 3
So 17512-83-3 is a valid CAS Registry Number.
