Check Digit Verification of cas no

The CAS Registry Mumber 266348-52-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,6,3,4 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 266348-52:
(8*2)+(7*6)+(6*6)+(5*3)+(4*4)+(3*8)+(2*5)+(1*2)=161
161 % 10 = 1
So 266348-52-1 is a valid CAS Registry Number.
