403616-28-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 403616-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,3,6,1 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 403616-28:
(8*4)+(7*0)+(6*3)+(5*6)+(4*1)+(3*6)+(2*2)+(1*8)=114
114 % 10 = 4
So 403616-28-4 is a valid CAS Registry Number.

Aryl radical cyclisation approach to highly substituted oxindoles related to mitomycins
Jones,Storey
, p. 7797 - 7798 (2007/10/02)
Radical cyclisation of the hexa-substituted aromatic compounds 8 and 17 leads to highly substituted oxindoles 9 and 18 respectively in excellent yields. Oxindole 18 carries the correct substitution pattern for ring-A of mitomycin A.
