Check Digit Verification of cas no

The CAS Registry Mumber 138355-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,5 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138355-89:
(8*1)+(7*3)+(6*8)+(5*3)+(4*5)+(3*5)+(2*8)+(1*9)=152
152 % 10 = 2
So 138355-89-2 is a valid CAS Registry Number.
