891718-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 891718-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,1,7,1 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 891718-99:
(8*8)+(7*9)+(6*1)+(5*7)+(4*1)+(3*8)+(2*9)+(1*9)=223
223 % 10 = 3
So 891718-99-3 is a valid CAS Registry Number.

England, Dylan B.,Magolan, Jakob,Kerr, Michael A.
, p. 2209 - 2212 (2007/10/03)
The synthesis of the highly substituted indole portion of the complex tremorgenic natural products lolicine A and B is presented. The Diels-Alder reaction of a quinone monoimine enables the synthesis of an appropriately substituted indole. The key step in
