Check Digit Verification of cas no

The CAS Registry Mumber 1532520-75-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,3,2,5,2 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1532520-75:
(9*1)+(8*5)+(7*3)+(6*2)+(5*5)+(4*2)+(3*0)+(2*7)+(1*5)=134
134 % 10 = 4
So 1532520-75-4 is a valid CAS Registry Number.

Pd-catalyzed Oxidative coupling of Enamides and Alkynes for synthesis of substituted Pyrroles

Zhao, Mi-Na,Ren, Zhi-Hui,Wang, Yao-Yu,Guan, Zheng-Hui

, p. 608 - 611 (2014)

A novel and efficient palladium(II)-catalyzed alkenyl C-H activation oxidative annulation of enamides with alkynes for the synthesis of substituted pyrroles has been developed. The reaction tolerates a wide range of functional groups and is a reliable method for the synthesis of triaryl-substituted pyrroles in high yields.
