Check Digit Verification of cas no
The CAS Registry Mumber 1994-56-5 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 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1994-56:
(6*1)+(5*9)+(4*9)+(3*4)+(2*5)+(1*6)=115
115 % 10 = 5
So 1994-56-5 is a valid CAS Registry Number.
