Check Digit Verification of cas no
The CAS Registry Mumber 306281-50-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,6,2,8 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 306281-50:
(8*3)+(7*0)+(6*6)+(5*2)+(4*8)+(3*1)+(2*5)+(1*0)=115
115 % 10 = 5
So 306281-50-5 is a valid CAS Registry Number.

A total synthesis of (+)-zaragozic acid C is described. Key steps are an acid-mediated acetonide deprotection-dithiane removal-ketalisation procedure, providing selectively the 2,8-dioxabicyclo[3.2.1]octane core of the natural product, and the simultaneou
