Check Digit Verification of cas no

The CAS Registry Mumber 1120370-71-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,0,3,7 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1120370-71:
(9*1)+(8*1)+(7*2)+(6*0)+(5*3)+(4*7)+(3*0)+(2*7)+(1*1)=89
89 % 10 = 9
So 1120370-71-9 is a valid CAS Registry Number.

Silver nitrate catalysed tandem reactions of o-ethynylanilines with aryl aldehydes: Selective one-pot synthesis of bis(indolyl)methanes

Hu, Bo-Lun,Hu, Hua-Nan,Tang, Ri-Yuan

, p. 468 - 471 (2012)

Bis(indolyl)methanes are an important class of indole derivatives that have been widely used in medical treatments. A novel silver nitrate-catalysed one-pot synthesis of bis(indolyl)methanes has been developed. In the presence of silver nitrate, cycloisomerisation and bis-addition of o-ethynylanilines with aromatic aldehydes were carried out efficiently to afford the corresponding bis(indolyl)methanes in good to excellent yields.
