Check Digit Verification of cas no

The CAS Registry Mumber 137601-22-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,0 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 137601-22:
(8*1)+(7*3)+(6*7)+(5*6)+(4*0)+(3*1)+(2*2)+(1*2)=110
110 % 10 = 0
So 137601-22-0 is a valid CAS Registry Number.

Regioselectivity in electrophilic substitution of 5-aminoindoles and 5-aminoindolines: Synthesis of pyrrolo[3,2-e]indoles and isomeric pyrrolo[2,3-f]indoles

Prasad,Burchat,Weeratunga,Watts,Dmitrienko

, p. 5035 - 5038 (1991)

An FMO Theory prediction that 5-aminoindoles, 5, should react with electrophiles preferentially at C4 rather than at C6 whereas N1-acyl-5-aminoindolones, 6, should react preferentially at C6 rather than C4 is borne out experimentally by the synthesis of a pyrrolo[3,2-e]indole from 5 and pyrrolo[2,3-f]indoles from 6.
