Check Digit Verification of cas no
The CAS Registry Mumber 104783-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,7,8 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 104783-99:
(8*1)+(7*0)+(6*4)+(5*7)+(4*8)+(3*3)+(2*9)+(1*9)=135
135 % 10 = 5
So 104783-99-5 is a valid CAS Registry Number.
