Check Digit Verification of cas no
The CAS Registry Mumber 1172938-55-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,2,9,3 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1172938-55:
(9*1)+(8*1)+(7*7)+(6*2)+(5*9)+(4*3)+(3*8)+(2*5)+(1*5)=174
174 % 10 = 4
So 1172938-55-4 is a valid CAS Registry Number.
