Check Digit Verification of cas no
The CAS Registry Mumber 90301-42-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,0 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90301-42:
(7*9)+(6*0)+(5*3)+(4*0)+(3*1)+(2*4)+(1*2)=91
91 % 10 = 1
So 90301-42-1 is a valid CAS Registry Number.
