83355-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83355-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,5 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83355-91:
(7*8)+(6*3)+(5*3)+(4*5)+(3*5)+(2*9)+(1*1)=143
143 % 10 = 3
So 83355-91-3 is a valid CAS Registry Number.
