108546-04-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108546-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,5,4 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 108546-04:
(8*1)+(7*0)+(6*8)+(5*5)+(4*4)+(3*6)+(2*0)+(1*4)=119
119 % 10 = 9
So 108546-04-9 is a valid CAS Registry Number.
