696574-70-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 696574-70-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,6,5,7 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 696574-70:
(8*6)+(7*9)+(6*6)+(5*5)+(4*7)+(3*4)+(2*7)+(1*0)=226
226 % 10 = 6
So 696574-70-6 is a valid CAS Registry Number.

, p. 3689 - 3694 (2007/10/03)
Starting from shikimic acid, the total synthesis of zeylenone was studied. The product was proved to be the (+)antipode of zeylenone through analysis and comparison of their respective spectra (including NMR, MS, IR and CD) and optical data. The absolute
