Check Digit Verification of cas no

The CAS Registry Mumber 138804-61-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,0 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138804-61:
(8*1)+(7*3)+(6*8)+(5*8)+(4*0)+(3*4)+(2*6)+(1*1)=142
142 % 10 = 2
So 138804-61-2 is a valid CAS Registry Number.
