The CAS Registry Mumber 174277-73-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,2,7 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 174277-73:
(8*1)+(7*7)+(6*4)+(5*2)+(4*7)+(3*7)+(2*7)+(1*3)=157
157 % 10 = 7
So 174277-73-7 is a valid CAS Registry Number.
