Check Digit Verification of cas no

The CAS Registry Mumber 1640005-65-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,0,0,0 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1640005-65:
(9*1)+(8*6)+(7*4)+(6*0)+(5*0)+(4*0)+(3*5)+(2*6)+(1*5)=117
117 % 10 = 7
So 1640005-65-7 is a valid CAS Registry Number.

Regioselective hydrations of 1-aryl-3-en-1-ynes using gold and platinum catalysts: Selective production of 2-en-1-ones and 3-en-1-ones

Mokar, Bhanudas Dattatray,Liu, Rai-Shung

supporting information, p. 8966 - 8969 (2014/08/05)

Regiocontrolled hydrations of 1-aryl-3-en-1-ynes have been accomplished with IPrAuOTf and PtCl2/CO to yield 3-en-1-ones and 2-en-1-ones efficiently; our experimental data indicates that the sizes of catalysts play an important role. This journa
