851912-97-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 851912-97-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,9,1 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 851912-97:
(8*8)+(7*5)+(6*1)+(5*9)+(4*1)+(3*2)+(2*9)+(1*7)=185
185 % 10 = 5
So 851912-97-5 is a valid CAS Registry Number.

A Total Synthesis of Horsfiline via Aryl Radical Cyclisation
Jones, Keith,Wilkinson, James
, p. 1767 - 1769 (2007/10/02)
Cyclisation of 15 via the derived aryl radical leads to spiropyrrolidinyl-oxindole 16, which is converted in three steps into the oxindole alkaloid horsfiline 3.
