Check Digit Verification of cas no
The CAS Registry Mumber 73019-17-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,0,1 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73019-17:
(7*7)+(6*3)+(5*0)+(4*1)+(3*9)+(2*1)+(1*7)=107
107 % 10 = 7
So 73019-17-7 is a valid CAS Registry Number.
