Check Digit Verification of cas no
The CAS Registry Mumber 143993-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,9 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143993-90:
(8*1)+(7*4)+(6*3)+(5*9)+(4*9)+(3*3)+(2*9)+(1*0)=162
162 % 10 = 2
So 143993-90-2 is a valid CAS Registry Number.
