55515-39-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55515-39-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,1 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 55515-39:
(7*5)+(6*5)+(5*5)+(4*1)+(3*5)+(2*3)+(1*9)=124
124 % 10 = 4
So 55515-39-4 is a valid CAS Registry Number.

Westphalen-type rearrangement of a 9α-hydroxy-11-ketone derived from lanosterol resulted in formation of two 19(10->9β)abeo-lanostenes representing the first lanostane-to-cucurbitane transformation.A novel ring A aromatic 9,10-seco derivative was formed a
