Check Digit Verification of cas no
The CAS Registry Mumber 420120-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,0,1,2 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 420120-99:
(8*4)+(7*2)+(6*0)+(5*1)+(4*2)+(3*0)+(2*9)+(1*9)=86
86 % 10 = 6
So 420120-99-6 is a valid CAS Registry Number.
