871502-97-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 871502-97-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,5,0 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 871502-97:
(8*8)+(7*7)+(6*1)+(5*5)+(4*0)+(3*2)+(2*9)+(1*7)=175
175 % 10 = 5
So 871502-97-5 is a valid CAS Registry Number.
