Check Digit Verification of cas no

The CAS Registry Mumber 1258442-40-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,4,4 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1258442-40:
(9*1)+(8*2)+(7*5)+(6*8)+(5*4)+(4*4)+(3*2)+(2*4)+(1*0)=158
158 % 10 = 8
So 1258442-40-8 is a valid CAS Registry Number.

supporting information; experimental part, p. 8219 - 8221 (2010/12/20)

A simple acid-resistant hydrophobic tag, which can be removed rapidly in a single-step procedure after overall peptide synthesis, has been developed to accomplish practical solution-phase synthesis of a 15-mer antagonistic peptide of TNF-α (A-TNF-α). Hydrophobically tagged peptides can be separated as precipitates at each step by addition of a polar organic solvent.
