Check Digit Verification of cas no

The CAS Registry Mumber 1361403-83-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,6,1,4,0 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1361403-83:
(9*1)+(8*3)+(7*6)+(6*1)+(5*4)+(4*0)+(3*3)+(2*8)+(1*3)=129
129 % 10 = 9
So 1361403-83-9 is a valid CAS Registry Number.

Phosphorus-containing Lewis base catalyzed highly regioselective cyclization of isatin derived electron-deficient alkenes with but-3-yn-2-one

Lian, Zhong,Wei, Yin,Shi, Min

, p. 2401 - 2408 (2012/04/10)

In this paper, we reported that phosphorus-containing Lewis bases catalyzed [4+2] cyclization of N-protected isatin derived electron-deficient alkenes with but-3-yn-2-one could proceed smoothly to give the corresponding dihydropyrano[2,3-b]indoles in good
