Check Digit Verification of cas no
The CAS Registry Mumber 4544-19-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,4 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4544-19:
(6*4)+(5*5)+(4*4)+(3*4)+(2*1)+(1*9)=88
88 % 10 = 8
So 4544-19-8 is a valid CAS Registry Number.
