Check Digit Verification of cas no

The CAS Registry Mumber 137362-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,6 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137362-90:
(8*1)+(7*3)+(6*7)+(5*3)+(4*6)+(3*2)+(2*9)+(1*0)=134
134 % 10 = 4
So 137362-90-4 is a valid CAS Registry Number.
