81355-43-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81355-43-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,5 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81355-43:
(7*8)+(6*1)+(5*3)+(4*5)+(3*5)+(2*4)+(1*3)=123
123 % 10 = 3
So 81355-43-3 is a valid CAS Registry Number.
