862297-62-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 862297-62-9 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, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 862297-62:
(8*8)+(7*6)+(6*2)+(5*2)+(4*9)+(3*7)+(2*6)+(1*2)=199
199 % 10 = 9
So 862297-62-9 is a valid CAS Registry Number.

A total synthesis of (±)-α-cyclopiazonic acid using a cationic cascade as a key step
Griffiths-Jones, Charlotte M.,Knight, David W.
, p. 8515 - 8528 (2011/11/29)
The indole alkaloid α-cyclopiazonic acid 1 has been synthesised by a route, which features at its core an acid-catalysed cationic cascade cyclisation terminated by a sulfonamide group.
