Check Digit Verification of cas no

The CAS Registry Mumber 648418-75-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,8,4,1 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 648418-75:
(8*6)+(7*4)+(6*8)+(5*4)+(4*1)+(3*8)+(2*7)+(1*5)=191
191 % 10 = 1
So 648418-75-1 is a valid CAS Registry Number.
