77821-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77821-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,2 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77821-18:
(7*7)+(6*7)+(5*8)+(4*2)+(3*1)+(2*1)+(1*8)=152
152 % 10 = 2
So 77821-18-2 is a valid CAS Registry Number.

THE SYNTHESIS OF 8-ARYL-1,2,3,4-TETRAHYDROISOQUINOLINES
Hara, Hiroshi,Hoshino, Osamu,Umezawa, Bunsuke
, p. 911 - 914 (2007/10/02)
Treatment of a mixture of the p-quinol acetate (1a) and aryl alkyl ethers with trifluoroacetic acid gave the 8-aryl-1,2,3,4-tetrahydroisoquinolines (5a-f) in good yields.Similar reaction of 1a and corypalline (2a) afforded the corrypalline dimer (7).
