Check Digit Verification of cas no

The CAS Registry Mumber 158809-26-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,8,0 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 158809-26:
(8*1)+(7*5)+(6*8)+(5*8)+(4*0)+(3*9)+(2*2)+(1*6)=168
168 % 10 = 8
So 158809-26-8 is a valid CAS Registry Number.

Amide bond formation via pentafluorothiophenyl active esters

Davis, Anthony P.,Walsh, John J.

, p. 4865 - 4868 (1994)

A number of pentafluorothiophenyl (PFTP) esters were shown to be useful acyl donors for amide bond formation, being non-polar, stable to chromatography and extended storage, but sufficiently active for use with relatively unreactive acyl groups. In partic
