Check Digit Verification of cas no
The CAS Registry Mumber 105098-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,0,9 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 105098-72:
(8*1)+(7*0)+(6*5)+(5*0)+(4*9)+(3*8)+(2*7)+(1*2)=114
114 % 10 = 4
So 105098-72-4 is a valid CAS Registry Number.
