Check Digit Verification of cas no
The CAS Registry Mumber 521-03-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,2 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 521-03:
(5*5)+(4*2)+(3*1)+(2*0)+(1*3)=39
39 % 10 = 9
So 521-03-9 is a valid CAS Registry Number.

A maximum of five deuterium atoms was incorporated into the 24β-ethylsterols, 22-dihydro-25-dehydrochondrillasterol and 22-dihydrochondrillasterol, in tissue cultures of trichisanthes kirilowii incubated with L-methionine.The results proved that a 24-ethylidene intermediate is not involved in the biosynthesis of 24β-ethylsterols in T.kirilowii. Key Word Index: Trichosanthes kirilowii; Cucurbitaceae; tissue culture; biosynthesis, phytosterols; 22-dihydrochondrillasterol; 22-dihydro-25-dehydrochondrillasterol; methionine.
