206766-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 206766-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,7,6 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 206766-50:
(8*2)+(7*0)+(6*6)+(5*7)+(4*6)+(3*6)+(2*5)+(1*0)=139
139 % 10 = 9
So 206766-50-9 is a valid CAS Registry Number.

A synthesis of (+)-9a-desmethoxymitomycin A via aziridinyl radical cyclization
Ziegler, Frederick E.,Berlin, Michael Y.
, p. 2455 - 2458 (2007/10/03)
A synthesis of (+)-desmethoxymitomycin A is described. The critical step is a highly stereoselective cyclization of an aziridinyl radical to afford a tetracycle having the same relative and absolute stereochemistry as mitomycin A and C.
