Check Digit Verification of cas no

The CAS Registry Mumber 850146-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,1,4 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 850146-56:
(8*8)+(7*5)+(6*0)+(5*1)+(4*4)+(3*6)+(2*5)+(1*6)=154
154 % 10 = 4
So 850146-56-4 is a valid CAS Registry Number.

Novel erythromycin A derivatives: Synthesis of 11,12-benzoxazine ketolides

Zhu, Bin,Maden, Amy,Macielag, Mark J.

, p. 1783 - 1785 (2007/10/03)

A novel series of 11,12-benzoxazine ketolide derivatives of erythromycin A has been synthesized. The C11,C12-benzoxazine structure was constructed stereoselectively through an intramolecular Michael addition of a C12-O-(2-aminophenyl) group to the enone functionality of the 10,11-anhydro erythromycin A derivative 3.
