22550-76-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22550-76-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,5,5 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 22550-76:
(7*2)+(6*2)+(5*5)+(4*5)+(3*0)+(2*7)+(1*6)=91
91 % 10 = 1
So 22550-76-1 is a valid CAS Registry Number.

The petrol extract of the whole plant of Adiantum lunuactum yielded a new hopane triterpenoid characterized as 6α-acetoxy-16β,22-dihydroxy-3-ketoisohopane, along with the known 3β,6α,16β,22-tetrahydroxyisohopane (mollugogenol A). The structures were elucidated by spectral as well as chemical studies.
