Check Digit Verification of cas no
The CAS Registry Mumber 483-20-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,8 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 483-20:
(5*4)+(4*8)+(3*3)+(2*2)+(1*0)=65
65 % 10 = 5
So 483-20-5 is a valid CAS Registry Number.

Development of a practical one-pot synthesis of indigo from indole
Yamamoto, Yoshihiro,Inoue, Yoshihisa,Takaki, Usaji,Suzuki, Hiroharu
experimental part, p. 82 - 89 (2011/04/12)
A novel and highly practical one-pot synthesis of indigo from indole via 3-position selective oxidation and dimerization of the indole framework was developed. Using 0.1 mol% of molybdenum complex and 2.2 equivalents of cumene hydroperoxide in tert-butyl alcohol, the reaction was complete in 7 h and pure indigo was obtained in 81% yield as a deep-blue solid just by filtration. The described one-step method renders the pure indigo readily available on a large scale using only inexpensive raw materials.
