6201-91-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6201-91-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,0 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6201-91:
(6*6)+(5*2)+(4*0)+(3*1)+(2*9)+(1*1)=68
68 % 10 = 8
So 6201-91-8 is a valid CAS Registry Number.
