133218-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133218-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,2,1 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 133218-81:
(8*1)+(7*3)+(6*3)+(5*2)+(4*1)+(3*8)+(2*8)+(1*1)=102
102 % 10 = 2
So 133218-81-2 is a valid CAS Registry Number.
