37936-58-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 37936-58-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,9,3 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 37936-58:
(7*3)+(6*7)+(5*9)+(4*3)+(3*6)+(2*5)+(1*8)=156
156 % 10 = 6
So 37936-58-6 is a valid CAS Registry Number.

A series of guaianolides such as mokko lactone, dehydrocostus lactone, and eremanthin which posses a common structural unit in A ring have been synthesized from 1-oxoeudesm-2-eno-13,6α-lactone in 7 steps.The key step involves solvolytic rearrangement of 1β-mesyloxyeudesm-4(14)-eno-13,6α-lactone.
