80817-55-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80817-55-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,8,1 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80817-55:
(7*8)+(6*0)+(5*8)+(4*1)+(3*7)+(2*5)+(1*5)=136
136 % 10 = 6
So 80817-55-6 is a valid CAS Registry Number.
