Check Digit Verification of cas no

The CAS Registry Mumber 65481-03-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,4,8 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 65481-03:
(7*6)+(6*5)+(5*4)+(4*8)+(3*1)+(2*0)+(1*3)=130
130 % 10 = 0
So 65481-03-0 is a valid CAS Registry Number.

Approaches to the Synthesis of the Mitomycins. A Route to the Mitosanes Involving Activated Cyclopropanes

Danishefsky, Samuel,Regan, John,Doehner, Robert

, p. 5255 - 5261 (2007/10/02)

The synthesis of (9R*,9aS*)-9-methyl>-9,9a-dihydro-5,7,8-trimethoxy-6-methyl-3H-pyrroloindole has been achieved.The key reaction involves intramolecular nucleophilic displacement of an activated cyclopropane.The modification of the electrophilicity of the diactivated cyclopropane by alteration of the geometric relationship of the carbonyl linkages with the bent bonds of the ring is an important feature of the study.
