108940-48-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108940-48-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,9,4 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 108940-48:
(8*1)+(7*0)+(6*8)+(5*9)+(4*4)+(3*0)+(2*4)+(1*8)=133
133 % 10 = 3
So 108940-48-3 is a valid CAS Registry Number.
