189271-52-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189271-52-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,2,7 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 189271-52:
(8*1)+(7*8)+(6*9)+(5*2)+(4*7)+(3*1)+(2*5)+(1*2)=171
171 % 10 = 1
So 189271-52-1 is a valid CAS Registry Number.
