Check Digit Verification of cas no

The CAS Registry Mumber 22682-13-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,6,8 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 22682-13:
(7*2)+(6*2)+(5*6)+(4*8)+(3*2)+(2*1)+(1*3)=99
99 % 10 = 9
So 22682-13-9 is a valid CAS Registry Number.

, p. 1122 - 1133 (2005)

(Chemical Equation Presented) Diels-Alder reactions of 3- and 5-halo-subsituted 2(H)-pyran-2-ones with both electron-rich and electron-deficient dienophiles afford stable and readily isolable bridged bicyclic lactone cycloadducts. These cycloadditions pro
