Check Digit Verification of cas no

The CAS Registry Mumber 816463-31-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,6,4,6 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 816463-31:
(8*8)+(7*1)+(6*6)+(5*4)+(4*6)+(3*3)+(2*3)+(1*1)=167
167 % 10 = 7
So 816463-31-7 is a valid CAS Registry Number.

Palladium-catalyzed tandem reaction of yne-propargylic carbonates with boronic acids: A simple method for the synthesis of fused aromatic rings through allene-mediated electrocyclization

Wang, Feng,Tong, Xiaofeng,Cheng, Jiang,Zhang, Zhaoguo

, p. 5338 - 5344 (2007/10/03)

The palladium-catalyzed tandem reactions of yne-propargylic carbonates with aryl boronic acids, 2-furyl boronic acid, and 2-thiopheneboronic acid, followed by 6π-electrocyclization to give fused ring aromatic products such as naphthalene, benzofuran, and
