Check Digit Verification of cas no
The CAS Registry Mumber 6633-90-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,3 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6633-90:
(6*6)+(5*6)+(4*3)+(3*3)+(2*9)+(1*0)=105
105 % 10 = 5
So 6633-90-5 is a valid CAS Registry Number.
