Check Digit Verification of cas no
The CAS Registry Mumber 320381-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,0,3,8 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 320381-90:
(8*3)+(7*2)+(6*0)+(5*3)+(4*8)+(3*1)+(2*9)+(1*0)=106
106 % 10 = 6
So 320381-90-6 is a valid CAS Registry Number.
