Check Digit Verification of cas no
The CAS Registry Mumber 120428-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,4,2 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120428-80:
(8*1)+(7*2)+(6*0)+(5*4)+(4*2)+(3*8)+(2*8)+(1*0)=90
90 % 10 = 0
So 120428-80-0 is a valid CAS Registry Number.
