Check Digit Verification of cas no
The CAS Registry Mumber 112545-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,5,4 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 112545-69:
(8*1)+(7*1)+(6*2)+(5*5)+(4*4)+(3*5)+(2*6)+(1*9)=104
104 % 10 = 4
So 112545-69-4 is a valid CAS Registry Number.
