Check Digit Verification of cas no

The CAS Registry Mumber 187085-39-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,0,8 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 187085-39:
(8*1)+(7*8)+(6*7)+(5*0)+(4*8)+(3*5)+(2*3)+(1*9)=168
168 % 10 = 8
So 187085-39-8 is a valid CAS Registry Number.

A simple and general synthesis of 4-oxo-4,5,6,7-tetrahydroindoles via a novel intramolecular 1,3-dipolar cycloaddition approach

Hutchison, Darrell R.,Nayyar, Naresh K.,Martinelli, Michael J.

, p. 2887 - 2890 (1996)

A general synthesis of 4-keto-4,5,6,7-tetrahydroindoles 6-12 has been achieved in two steps using a new intramolecular 1,3-dipolar cycloaddition approach in moderate yields (45-60%). The potential of this methodology is demonstrated by the synthesis of a mitomycin skeleton (15) and a topoisomerase-1 inhibitor skeleton (17).
