875439-61-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 875439-61-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,5,4,3 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 875439-61:
(8*8)+(7*7)+(6*5)+(5*4)+(4*3)+(3*9)+(2*6)+(1*1)=215
215 % 10 = 5
So 875439-61-5 is a valid CAS Registry Number.
