Check Digit Verification of cas no
The CAS Registry Mumber 20993-63-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,9 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20993-63:
(7*2)+(6*0)+(5*9)+(4*9)+(3*3)+(2*6)+(1*3)=119
119 % 10 = 9
So 20993-63-9 is a valid CAS Registry Number.
