862297-58-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 862297-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,2,9 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 862297-58:
(8*8)+(7*6)+(6*2)+(5*2)+(4*9)+(3*7)+(2*5)+(1*8)=203
203 % 10 = 3
So 862297-58-3 is a valid CAS Registry Number.

A total synthesis of (±)-α-cyclopiazonic acid using a cationic cascade
Haskins, Charlotte M.,Knight, David W.
, p. 3162 - 3164 (2008/02/12)
The indolic terpene alkaloid α-cyclopiazonic acid 1 has been prepared in 11 steps from indole-4-methanol 6; the key step is a carbocationic cascade, terminated by a 4-nitrosulfonamide group and initiated by benzylic carbocation formation directly from the
