39863-70-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39863-70-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,8,6 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 39863-70:
(7*3)+(6*9)+(5*8)+(4*6)+(3*3)+(2*7)+(1*0)=162
162 % 10 = 2
So 39863-70-2 is a valid CAS Registry Number.

, (2019/11/26)

An efficient total synthesis of scrodentoid A was accomplished starting from a Hagemann's ester and a substituted (2-bromoethyl)benzene. Key reactions in this synthesis include C-alkylation of the Hagemann's ester, 6-endo-Trig cationic cyclization of an enone and Lewis acid promoted isomerization of a cis-fused ketone.
