Check Digit Verification of cas no

The CAS Registry Mumber 727425-77-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,7,4,2 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 727425-77:
(8*7)+(7*2)+(6*7)+(5*4)+(4*2)+(3*5)+(2*7)+(1*7)=176
176 % 10 = 6
So 727425-77-6 is a valid CAS Registry Number.

Bi(III)-catalyzed intermolecular reactions of (Z)-pent-2-en-4-yl acetates with ethynylarenes for the construction of multisubstituted fluorene skeletons through a cascade electrophilic addition/cycloisomerization sequence

Wang, Xiang-Chuan,Yan, Ru-Long,Zhong, Mei-Jin,Liang, Yong-Min

experimental part, p. 2064 - 2068 (2012/04/04)

A Bi(III)-catalyzed method for the synthesis of highly conjugated aromatic multisubstituted fluorene with (Z)-pent-2-en-4-yl acetates and ethynylarenes via domino reaction is described. In this process, the reaction appears to be very general and suitable
