881998-72-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 881998-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,9,9 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 881998-72:
(8*8)+(7*8)+(6*1)+(5*9)+(4*9)+(3*8)+(2*7)+(1*2)=247
247 % 10 = 7
So 881998-72-7 is a valid CAS Registry Number.
