881897-27-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 881897-27-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,8,9 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 881897-27:
(8*8)+(7*8)+(6*1)+(5*8)+(4*9)+(3*7)+(2*2)+(1*7)=234
234 % 10 = 4
So 881897-27-4 is a valid CAS Registry Number.
