186647-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 186647-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,6,4 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 186647-71:
(8*1)+(7*8)+(6*6)+(5*6)+(4*4)+(3*7)+(2*7)+(1*1)=182
182 % 10 = 2
So 186647-71-2 is a valid CAS Registry Number.
