7687-09-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7687-09-4 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 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7687-09:
(6*7)+(5*6)+(4*8)+(3*7)+(2*0)+(1*9)=134
134 % 10 = 4
So 7687-09-4 is a valid CAS Registry Number.
