61692-89-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61692-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,6,9 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 61692-89:
(7*6)+(6*1)+(5*6)+(4*9)+(3*2)+(2*8)+(1*9)=145
145 % 10 = 5
So 61692-89-5 is a valid CAS Registry Number.
