Check Digit Verification of cas no
The CAS Registry Mumber 130733-83-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,3 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 130733-83:
(8*1)+(7*3)+(6*0)+(5*7)+(4*3)+(3*3)+(2*8)+(1*3)=104
104 % 10 = 4
So 130733-83-4 is a valid CAS Registry Number.
