Check Digit Verification of cas no

The CAS Registry Mumber 1241383-59-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,1,3,8 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1241383-59:
(9*1)+(8*2)+(7*4)+(6*1)+(5*3)+(4*8)+(3*3)+(2*5)+(1*9)=134
134 % 10 = 4
So 1241383-59-4 is a valid CAS Registry Number.

Base-promoted one-pot tandem reaction of 3-(1-alkynyl)chromones under microwave irradiation to functionalized amino-substituted xanthones

Liu, Yang,Huang, Liping,Xie, Fuchun,Hu, Youhong

supporting information; experimental part, p. 6304 - 6307 (2010/11/17)

Figure presented. A base-promoted one-pot tandem reaction has been developed from 3-(1-alkynyl)chromones with various acetonitriles to afford functionalized amino-substituted xanthones 3 under microwave irradiation. This tandem process involves multiple reactions, such as Michael addition/ cyclization/1,2-addition, without a transition metal catalyst. This method provides an efficient approach to build up natural product-like diversified amino-substituted xanthone scaffolds rapidly.
