Check Digit Verification of cas no

The CAS Registry Mumber 73986-27-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,9,8 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73986-27:
(7*7)+(6*3)+(5*9)+(4*8)+(3*6)+(2*2)+(1*7)=173
173 % 10 = 3
So 73986-27-3 is a valid CAS Registry Number.

The effect of substitution of the pyrrolo- and indolo-N atoms in tetrahydronaltrindole (TNTI), tetrahydrooxymorphindole (TOMI), and 17-cyclopropylmethyl-3,14-dihydroxy-4,5-epoxy-4′-phenyl-6,7:2′, 3′-pyrrolomorphinan (4) is reported. In opioid functional a

4'-Arylpyrrolomorphinans: effect of a pyrrolo-N-benzyl substituent in enhancing delta-opioid antagonist activity.

Srivastava, Sanjay K,Husbands, Stephen M,Aceto, Mario D,Miller, Carl N,Traynor, John R,Lewis, John W

, p. 537 - 540 (2002)

A new method for the preparation of N-benzylpyrrolomorphinans has been developed. Thus Michael reaction of the benzylimines of oxycodones and oxymorphones with nitrostyrenes gave a series of 4'-aryl-N-benzylpyrrolomorphinans. These were selective delta an
