Check Digit Verification of cas no

The CAS Registry Mumber 190258-37-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,2,5 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 190258-37:
(8*1)+(7*9)+(6*0)+(5*2)+(4*5)+(3*8)+(2*3)+(1*7)=138
138 % 10 = 8
So 190258-37-8 is a valid CAS Registry Number.
