110419-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 110419-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,4,1 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 110419-45:
(8*1)+(7*1)+(6*0)+(5*4)+(4*1)+(3*9)+(2*4)+(1*5)=79
79 % 10 = 9
So 110419-45-9 is a valid CAS Registry Number.

The keto ester 13 is predominantly cyclized to the 1,2-cis-hydroxy ester 16 under aprotic conditions.Dimethyl ether 16 is split to 17.Hydroxylation of 17 by bromination and hydrolysis affords the nogalamycin aglycon 19 with 2,4-trans-hydroxy groups.
