119100-84-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119100-84-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,1,0 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 119100-84:
(8*1)+(7*1)+(6*9)+(5*1)+(4*0)+(3*0)+(2*8)+(1*4)=94
94 % 10 = 4
So 119100-84-4 is a valid CAS Registry Number.

SHORT SYNTHESIS OF AZAFLUORENONE ALKALOIDS USING TARNSITION METAL-CATALYZED CROSS COUPLING TACTICS
Alves, T.,Oliveira, A. B. de,Snieckus, V.
, p. 2135 - 2136 (1988)
An efficient route to the azafluorenone alkaloids, onychine (1a) and 6-methoxyonychine (1b) based on Pd(O)-catalyzed cross coupling of arylboronic acids 4a, 4b and arylstannene 4c with a bromonicotinate ester 5 is described.
