69471-14-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69471-14-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,4,7 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 69471-14:
(7*6)+(6*9)+(5*4)+(4*7)+(3*1)+(2*1)+(1*4)=153
153 % 10 = 3
So 69471-14-3 is a valid CAS Registry Number.
