Check Digit Verification of cas no
The CAS Registry Mumber 13244-19-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,4 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13244-19:
(7*1)+(6*3)+(5*2)+(4*4)+(3*4)+(2*1)+(1*9)=74
74 % 10 = 4
So 13244-19-4 is a valid CAS Registry Number.
