Check Digit Verification of cas no

The CAS Registry Mumber 1211547-52-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,1,5,4 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1211547-52:
(9*1)+(8*2)+(7*1)+(6*1)+(5*5)+(4*4)+(3*7)+(2*5)+(1*2)=112
112 % 10 = 2
So 1211547-52-2 is a valid CAS Registry Number.
