Check Digit Verification of cas no

The CAS Registry Mumber 1251852-84-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,1,8,5 and 2 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1251852-84:
(9*1)+(8*2)+(7*5)+(6*1)+(5*8)+(4*5)+(3*2)+(2*8)+(1*4)=152
152 % 10 = 2
So 1251852-84-2 is a valid CAS Registry Number.
