Check Digit Verification of cas no

The CAS Registry Mumber 637040-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,0,4 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 637040-89:
(8*6)+(7*3)+(6*7)+(5*0)+(4*4)+(3*0)+(2*8)+(1*9)=152
152 % 10 = 2
So 637040-89-2 is a valid CAS Registry Number.
