Check Digit Verification of cas no
The CAS Registry Mumber 98664-54-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,6 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98664-54:
(7*9)+(6*8)+(5*6)+(4*6)+(3*4)+(2*5)+(1*4)=191
191 % 10 = 1
So 98664-54-1 is a valid CAS Registry Number.

SYNTHESIS OF N(2)-HYDROXY-1,2,3,4-TETRAHYDRO-β-CARBOLINES
Han, So-Yeop,Laksmikantham, M. V.,Cava, Michel P.
, p. 1671 - 1673 (2007/10/02)
N-Hydroxytryptamine condensed readily with series of aldehydes in the presence of a catalytic amount of acetic acid to give the corresponding nitrones (4a-f), which in turn were cyclized by hydrochloric acid to the stable N(2)-hydroxytetrahydro-β-carbolin
