Check Digit Verification of cas no
The CAS Registry Mumber 89231-90-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,2,3 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89231-90:
(7*8)+(6*9)+(5*2)+(4*3)+(3*1)+(2*9)+(1*0)=153
153 % 10 = 3
So 89231-90-3 is a valid CAS Registry Number.
