69859-84-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69859-84-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,8,5 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 69859-84:
(7*6)+(6*9)+(5*8)+(4*5)+(3*9)+(2*8)+(1*4)=203
203 % 10 = 3
So 69859-84-3 is a valid CAS Registry Number.
