Check Digit Verification of cas no

The CAS Registry Mumber 1229244-31-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,2,4 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1229244-31:
(9*1)+(8*2)+(7*2)+(6*9)+(5*2)+(4*4)+(3*4)+(2*3)+(1*1)=138
138 % 10 = 8
So 1229244-31-8 is a valid CAS Registry Number.

Generation of 3-(1H-isochromen-1-yl)-1H-indole via silver triflate-catalyzed tandem reaction of 2-alkynylbenzaldehyde with indole

experimental part, p. 1239 - 1249 (2011/05/14)

A facile and efficient method is developed for synthesis of 3-(1H-isochromen-1-yl)-1H-indole via silver triflate-catalyzed tandem reaction of 2-alkynylbenzaldehyde with indole. The reaction proceeds smoothly in DMF at room temperature with good substrate generality. The availability of the starting materials combined with mild reaction conditions and the high efficiency of this synthetic route would be attractive and beneficial for the focused library construction.
