2681-57-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2681-57-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,8 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2681-57:
(6*2)+(5*6)+(4*8)+(3*1)+(2*5)+(1*7)=94
94 % 10 = 4
So 2681-57-4 is a valid CAS Registry Number.
