108291-88-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108291-88-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,2,9 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 108291-88:
(8*1)+(7*0)+(6*8)+(5*2)+(4*9)+(3*1)+(2*8)+(1*8)=129
129 % 10 = 9
So 108291-88-9 is a valid CAS Registry Number.
