Check Digit Verification of cas no

The CAS Registry Mumber 119752-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,7,5 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 119752-20:
(8*1)+(7*1)+(6*9)+(5*7)+(4*5)+(3*2)+(2*2)+(1*0)=134
134 % 10 = 4
So 119752-20-4 is a valid CAS Registry Number.
