(3beta,5xi)-lanosta-7,9(11)-dien-3-ol is a triterpenoid alcohol, which means it is a member of a class of organic compounds derived from the precursor farnesyl pyrophosphate. It is commonly found in plants and can have various biological activities, including anti-inflammatory and anti-cancer properties. Additionally, it is also used in the production of certain pharmaceuticals and as a building block in organic synthesis.
Check Digit Verification of cas no
The CAS Registry Mumber 2644-75-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,4 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2644-75:
(6*2)+(5*6)+(4*4)+(3*4)+(2*7)+(1*5)=89
89 % 10 = 9
So 2644-75-9 is a valid CAS Registry Number.
