182571-86-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 182571-86-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,5,7 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 182571-86:
(8*1)+(7*8)+(6*2)+(5*5)+(4*7)+(3*1)+(2*8)+(1*6)=154
154 % 10 = 4
So 182571-86-4 is a valid CAS Registry Number.
