118083-55-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118083-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,0,8 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 118083-55:
(8*1)+(7*1)+(6*8)+(5*0)+(4*8)+(3*3)+(2*5)+(1*5)=119
119 % 10 = 9
So 118083-55-9 is a valid CAS Registry Number.
