Check Digit Verification of cas no
The CAS Registry Mumber 177534-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,5,3 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 177534-99:
(8*1)+(7*7)+(6*7)+(5*5)+(4*3)+(3*4)+(2*9)+(1*9)=175
175 % 10 = 5
So 177534-99-5 is a valid CAS Registry Number.
