881892-12-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 881892-12-2 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 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 881892-12:
(8*8)+(7*8)+(6*1)+(5*8)+(4*9)+(3*2)+(2*1)+(1*2)=212
212 % 10 = 2
So 881892-12-2 is a valid CAS Registry Number.
