The CAS Registry Mumber 1173296-30-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,2,9 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1173296-30:
(9*1)+(8*1)+(7*7)+(6*3)+(5*2)+(4*9)+(3*6)+(2*3)+(1*0)=154
154 % 10 = 4
So 1173296-30-4 is a valid CAS Registry Number.
