61231-75-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61231-75-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,2,3 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 61231-75:
(7*6)+(6*1)+(5*2)+(4*3)+(3*1)+(2*7)+(1*5)=92
92 % 10 = 2
So 61231-75-2 is a valid CAS Registry Number.
