61471-69-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61471-69-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,4,7 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 61471-69:
(7*6)+(6*1)+(5*4)+(4*7)+(3*1)+(2*6)+(1*9)=120
120 % 10 = 0
So 61471-69-0 is a valid CAS Registry Number.
