Check Digit Verification of cas no

The CAS Registry Mumber 1176778-10-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,6,7,7 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1176778-10:
(9*1)+(8*1)+(7*7)+(6*6)+(5*7)+(4*7)+(3*8)+(2*1)+(1*0)=191
191 % 10 = 1
So 1176778-10-1 is a valid CAS Registry Number.
