13398-79-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13398-79-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,9 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13398-79:
(7*1)+(6*3)+(5*3)+(4*9)+(3*8)+(2*7)+(1*9)=123
123 % 10 = 3
So 13398-79-3 is a valid CAS Registry Number.

, p. 5116 - 5124 (2007/10/02)
The anthracycline p-quinone unit has been replaced by a 1,4-di-N-oxide function in the first synthesis of a 7,9-dideoxyanthracyclinone hetero isostere. 4,11-Dimethoxy-9-(methoxycarbonyl)-7,8,9,10-tetrahydrobenzophenazine was synthesized and converted t
