Check Digit Verification of cas no

The CAS Registry Mumber 1383531-79-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,3,5,3 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1383531-79:
(9*1)+(8*3)+(7*8)+(6*3)+(5*5)+(4*3)+(3*1)+(2*7)+(1*9)=170
170 % 10 = 0
So 1383531-79-0 is a valid CAS Registry Number.

Enhancing the scope of the Diels-Alder reaction through isonitrile chemistry: Emergence of a new class of acyl-activated dienophiles

Townsend, Steven D.,Wu, Xiangyang,Danishefsky, Samuel J.

, p. 10659 - 10663 (2012)

α,β-Unsaturated imides, formylated at the nitrogen atom, comprise a new and valuable family of dienophiles for servicing Diels-Alder reactions. These systems are assembled through extension of recently discovered isonitrile chemistry to the domain of α,β-unsaturated acids. Cycloadditions are facilitated by Et2AlCl, presumably via chelation between the two carbonyl groups of the N-formyl amide. Applications of the isonitrile/Diels-Alder logic to the IMDA reaction, as well as methodologies to modify the N-formyl amide of the resultant cycloaddition product, are described. It is expected that this easily executed chemistry will provide a significant enhancement for application of Diels-Alder reactions to many synthetic targets.
