108142-00-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108142-00-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,1,4 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 108142-00:
(8*1)+(7*0)+(6*8)+(5*1)+(4*4)+(3*2)+(2*0)+(1*0)=83
83 % 10 = 3
So 108142-00-3 is a valid CAS Registry Number.
