Check Digit Verification of cas no

The CAS Registry Mumber 646996-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,6,9,9 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 646996-53:
(8*6)+(7*4)+(6*6)+(5*9)+(4*9)+(3*6)+(2*5)+(1*3)=224
224 % 10 = 4
So 646996-53-4 is a valid CAS Registry Number.

Synthesis of functionalized 1-azaspirocyclic cyclopentanones using bronsted acid or N-bromosuccinimide promoted ring expansions

Dake, Gregory R.,Fenster, Michael D. B.,Hurley, Paul B.,Patrick, Brian O.

, p. 5668 - 5675 (2004)

Azaspirocyclic ring systems are present in a variety of alkaloids. Functionalized 1-azaspirocyclopentanones (6, 7, 11, 12) can be efficiently constructed through semipinacol ring expansion reactions of 2-(1- hydroxycyclobutyl)-p-toluenesulfonylenamides (4
