2171-82-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2171-82-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,7 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2171-82:
(6*2)+(5*1)+(4*7)+(3*1)+(2*8)+(1*2)=66
66 % 10 = 6
So 2171-82-6 is a valid CAS Registry Number.
