Check Digit Verification of cas no

The CAS Registry Mumber 165281-74-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,5,2,8 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 165281-74:
(8*1)+(7*6)+(6*5)+(5*2)+(4*8)+(3*1)+(2*7)+(1*4)=143
143 % 10 = 3
So 165281-74-3 is a valid CAS Registry Number.

Photoinduced radical hydroperfluoroalkylation and the synthesis of fluorinated amino acids and peptides

Yajima, Tomoko,Yamaguchi, Kanako,Hirokane, Rie,Nogami, Emiko

, p. 1 - 7 (2013/06/05)

The photoinduced radical hydroperfluoroalkylation of unsaturated carboxylic acids using TTMSS as a H-donor was successfully developed. The stereoselective reaction using Oppolzer's camphorsultum was also achieved to give high stereoselectivity. The reaction was also effective for N-phthalimide- dehydroamino acid and the product was easily converted to the corresponding amino acid and a peptide derivative.
