161198-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161198-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,1,9 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 161198-52:
(8*1)+(7*6)+(6*1)+(5*1)+(4*9)+(3*8)+(2*5)+(1*2)=133
133 % 10 = 3
So 161198-52-3 is a valid CAS Registry Number.
