7681-94-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7681-94-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,8 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7681-94:
(6*7)+(5*6)+(4*8)+(3*1)+(2*9)+(1*4)=129
129 % 10 = 9
So 7681-94-9 is a valid CAS Registry Number.
