Check Digit Verification of cas no

The CAS Registry Mumber 1242156-54-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,1,5 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1242156-54:
(9*1)+(8*2)+(7*4)+(6*2)+(5*1)+(4*5)+(3*6)+(2*5)+(1*4)=122
122 % 10 = 2
So 1242156-54-2 is a valid CAS Registry Number.
