93349-68-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93349-68-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,3,4 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 93349-68:
(7*9)+(6*3)+(5*3)+(4*4)+(3*9)+(2*6)+(1*8)=159
159 % 10 = 9
So 93349-68-9 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The anthracycline p-quinone unit has been replaced by a 1,4-di-N-oxide function in the first synthesis of a 7,9-dideoxyanthracyclinone hetero isostere.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
