881920-19-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 881920-19-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,9,2 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 881920-19:
(8*8)+(7*8)+(6*1)+(5*9)+(4*2)+(3*0)+(2*1)+(1*9)=190
190 % 10 = 0
So 881920-19-0 is a valid CAS Registry Number.
