853415-52-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 853415-52-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,3,4,1 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 853415-52:
(8*8)+(7*5)+(6*3)+(5*4)+(4*1)+(3*5)+(2*5)+(1*2)=168
168 % 10 = 8
So 853415-52-8 is a valid CAS Registry Number.
