Check Digit Verification of cas no

The CAS Registry Mumber 1591803-47-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,9,1,8,0 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1591803-47:
(9*1)+(8*5)+(7*9)+(6*1)+(5*8)+(4*0)+(3*3)+(2*4)+(1*7)=182
182 % 10 = 2
So 1591803-47-2 is a valid CAS Registry Number.

Phosphine-catalyzed [3+2] cycloaddition reactions of azomethine imines with electron-deficient alkenes: A facile access to dinitrogen-fused heterocycles

Li, Zhen,Yu, Hao,Liu, Honglei,Zhang, Lei,Jiang, Hui,Wang, Bo,Guo, Hongchao

, p. 1731 - 1736 (2014/03/21)

An efficient method for the phosphine-catalyzed [3+2] cycloaddition reaction of azomethine imines with diphenylsulfonyl alkenes to give dinitrogen-fused bi- or tricyclic heterocyclic compounds in high yields has been described. Moreover, two phenylsulfony
