Check Digit Verification of cas no

The CAS Registry Mumber 73140-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,1,4 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73140-22:
(7*7)+(6*3)+(5*1)+(4*4)+(3*0)+(2*2)+(1*2)=94
94 % 10 = 4
So 73140-22-4 is a valid CAS Registry Number.

, p. 865 - 868 (1981)

In the presence of bis(maleic anhydride)(norbornene)palladium as a catalyst, two 1-alkene molecules, R-CH2-CH=CH2, were added regioselectively to dimethyl acetylenedicarboxylate in the syn addition mode to give dimethyl 2-(2-alkenyl)-3-alkylmaleates, R-CH
