Check Digit Verification of cas no

The CAS Registry Mumber 20886-50-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,8 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20886-50:
(7*2)+(6*0)+(5*8)+(4*8)+(3*6)+(2*5)+(1*0)=114
114 % 10 = 4
