Check Digit Verification of cas no
The CAS Registry Mumber 1996-54-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,9 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1996-54:
(6*1)+(5*9)+(4*9)+(3*6)+(2*5)+(1*4)=119
119 % 10 = 9
So 1996-54-9 is a valid CAS Registry Number.
