108217-08-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108217-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,2,1 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 108217-08:
(8*1)+(7*0)+(6*8)+(5*2)+(4*1)+(3*7)+(2*0)+(1*8)=99
99 % 10 = 9
So 108217-08-9 is a valid CAS Registry Number.
