6694-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6694-71-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,9 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6694-71:
(6*6)+(5*6)+(4*9)+(3*4)+(2*7)+(1*1)=129
129 % 10 = 9
So 6694-71-9 is a valid CAS Registry Number.
