Check Digit Verification of cas no
The CAS Registry Mumber 118171-08-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,1,7 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 118171-08:
(8*1)+(7*1)+(6*8)+(5*1)+(4*7)+(3*1)+(2*0)+(1*8)=107
107 % 10 = 7
So 118171-08-7 is a valid CAS Registry Number.

Synthesis of 2-Butenolide and Tetronic Acid Analogues of Thiolactomycin
Still, Ian W. J.,Drewery, Michael J.
, p. 290 - 295 (2007/10/02)
A synthetic route to the three lactone analogues 2a-c of the interesting antibiotic thiolactomycin (1a) is described.The synthetic strategy used is flexible in that it allows in principle for variation in the nature of the substituents introduced at C-2,
