7690-17-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7690-17-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,9 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7690-17:
(6*7)+(5*6)+(4*9)+(3*0)+(2*1)+(1*7)=117
117 % 10 = 7
So 7690-17-7 is a valid CAS Registry Number.
