Check Digit Verification of cas no

The CAS Registry Mumber 19859-12-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,5 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19859-12:
(7*1)+(6*9)+(5*8)+(4*5)+(3*9)+(2*1)+(1*2)=152
152 % 10 = 2
So 19859-12-2 is a valid CAS Registry Number.
