Check Digit Verification of cas no

The CAS Registry Mumber 820213-27-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,0,2,1 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 820213-27:
(8*8)+(7*2)+(6*0)+(5*2)+(4*1)+(3*3)+(2*2)+(1*7)=112
112 % 10 = 2
So 820213-27-2 is a valid CAS Registry Number.

Br?nsted acid TfOH-mediated reactions of methylenecyclopropanes with nitriles

Huang, Jin-Wen,Shi, Min

, p. 2343 - 2346 (2004)

In the presence of Br?nsted acid TfOH, methylenecyclopropanes react with nitriles to give [3+2] cycloaddition products in good to high yields along with Ritter reaction products. In many cases, [3+2] cycloaddition products are obtained as the major produc
