Check Digit Verification of cas no
The CAS Registry Mumber 1345202-53-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,5,2,0 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1345202-53:
(9*1)+(8*3)+(7*4)+(6*5)+(5*2)+(4*0)+(3*2)+(2*5)+(1*3)=120
120 % 10 = 0
So 1345202-53-0 is a valid CAS Registry Number.
