69945-16-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69945-16-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,4 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 69945-16:
(7*6)+(6*9)+(5*9)+(4*4)+(3*5)+(2*1)+(1*6)=180
180 % 10 = 0
So 69945-16-0 is a valid CAS Registry Number.
