90181-42-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90181-42-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,8 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90181-42:
(7*9)+(6*0)+(5*1)+(4*8)+(3*1)+(2*4)+(1*2)=113
113 % 10 = 3
So 90181-42-3 is a valid CAS Registry Number.
