19716-69-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19716-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,1 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19716-69:
(7*1)+(6*9)+(5*7)+(4*1)+(3*6)+(2*6)+(1*9)=139
139 % 10 = 9
So 19716-69-9 is a valid CAS Registry Number.
