Check Digit Verification of cas no

The CAS Registry Mumber 193560-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,5,6 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 193560-63:
(8*1)+(7*9)+(6*3)+(5*5)+(4*6)+(3*0)+(2*6)+(1*3)=153
153 % 10 = 3
So 193560-63-3 is a valid CAS Registry Number.

Molecular cascades. 1. Tandem cyclopropyl iminium ion rearrangement- [4+2] cycloaddition reactions

Boeckman Jr., Robert K.,Breining, Scott R.,Arvanitis, Argyrios

, p. 8941 - 8962 (2007/10/03)

A tandem cyclopropyliminium ion rearrangement-Hofmann elimination affords rapid access to 3-vinyl Δ2-pyrrolines in some cases bearing an unsaturated tether in good yield. The resulting dienamines subsequently undergo both inter-and intramolecular [4+2] cycloaddition reactions. Good yields were obtained for a number of cases of intramolecular intermolecular cycloaddition reactions affording cycloadducts in good yields with sufficiently reactive dienophiles such as fumarate, acrylate and methacrolein. Evidence suggests a non-concerted pathway for these cycloaddition reactions.
