196875-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 196875-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,8,7 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 196875-20:
(8*1)+(7*9)+(6*6)+(5*8)+(4*7)+(3*5)+(2*2)+(1*0)=194
194 % 10 = 4
So 196875-20-4 is a valid CAS Registry Number.
