Check Digit Verification of cas no

The CAS Registry Mumber 1218769-64-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,8,7,6 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1218769-64:
(9*1)+(8*2)+(7*1)+(6*8)+(5*7)+(4*6)+(3*9)+(2*6)+(1*4)=182
182 % 10 = 2
