491875-62-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 491875-62-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,1,8,7 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 491875-62:
(8*4)+(7*9)+(6*1)+(5*8)+(4*7)+(3*5)+(2*6)+(1*2)=198
198 % 10 = 8
So 491875-62-8 is a valid CAS Registry Number.
