Check Digit Verification of cas no

The CAS Registry Mumber 120642-12-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,6,4 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 120642-12:
(8*1)+(7*2)+(6*0)+(5*6)+(4*4)+(3*2)+(2*1)+(1*2)=78
78 % 10 = 8
So 120642-12-8 is a valid CAS Registry Number.
