853247-16-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 853247-16-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,3,2,4 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 853247-16:
(8*8)+(7*5)+(6*3)+(5*2)+(4*4)+(3*7)+(2*1)+(1*6)=172
172 % 10 = 2
So 853247-16-2 is a valid CAS Registry Number.
