Check Digit Verification of cas no

The CAS Registry Mumber 91757-48-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,5 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91757-48:
(7*9)+(6*1)+(5*7)+(4*5)+(3*7)+(2*4)+(1*8)=161
161 % 10 = 1
So 91757-48-1 is a valid CAS Registry Number.
