5681-91-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5681-91-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,8 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5681-91:
(6*5)+(5*6)+(4*8)+(3*1)+(2*9)+(1*1)=114
114 % 10 = 4
So 5681-91-4 is a valid CAS Registry Number.
