Check Digit Verification of cas no

The CAS Registry Mumber 263369-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,3,6 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 263369-18:
(8*2)+(7*6)+(6*3)+(5*3)+(4*6)+(3*9)+(2*1)+(1*8)=152
152 % 10 = 2
So 263369-18-2 is a valid CAS Registry Number.
