Check Digit Verification of cas no
The CAS Registry Mumber 157428-04-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,4,2 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 157428-04:
(8*1)+(7*5)+(6*7)+(5*4)+(4*2)+(3*8)+(2*0)+(1*4)=141
141 % 10 = 1
So 157428-04-1 is a valid CAS Registry Number.
