Check Digit Verification of cas no

The CAS Registry Mumber 89049-62-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,4 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89049-62:
(7*8)+(6*9)+(5*0)+(4*4)+(3*9)+(2*6)+(1*2)=167
167 % 10 = 7
So 89049-62-7 is a valid CAS Registry Number.
