Check Digit Verification of cas no

The CAS Registry Mumber 1271735-75-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,1,7,3 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1271735-75:
(9*1)+(8*2)+(7*7)+(6*1)+(5*7)+(4*3)+(3*5)+(2*7)+(1*5)=161
161 % 10 = 1
So 1271735-75-1 is a valid CAS Registry Number.
