882182-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 882182-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,2,1,8 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 882182-81:
(8*8)+(7*8)+(6*2)+(5*1)+(4*8)+(3*2)+(2*8)+(1*1)=192
192 % 10 = 2
So 882182-81-2 is a valid CAS Registry Number.
