Check Digit Verification of cas no

The CAS Registry Mumber 68384-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,3,8 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 68384-22:
(7*6)+(6*8)+(5*3)+(4*8)+(3*4)+(2*2)+(1*2)=155
155 % 10 = 5
So 68384-22-5 is a valid CAS Registry Number.

+-Nootkatone derivative

-

Paragraph 0007; 0013, (2017/08/27)

The invention discloses a preparation method for +-nootkatone derivative. The present invention uses the +-nootkatone derivative extracted from cedar leaves as the main material, a chemical compound II is obtained after the restoration through sodium borohydride, the chemical compound II reacts to obtain a chemical compound III and a chemical compound IV through the decomposition of enzymatic dynamics, or decomposes through dynamic kinetics to obtain a chemical compound III with more than 90% yield, a chemical compound V is obtained after hydrolyzing the chemical compound III. The present invention turns the latent chiral ketone group in +-nootkatone into a chirality hydroxy center, and splits further; the present invention has the characteristics of being simple in operation, being high in product yield and with good optics purity.
