Check Digit Verification of cas no

The CAS Registry Mumber 1274823-91-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,4,8,2 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1274823-91:
(9*1)+(8*2)+(7*7)+(6*4)+(5*8)+(4*2)+(3*3)+(2*9)+(1*1)=174
174 % 10 = 4
So 1274823-91-4 is a valid CAS Registry Number.
