Check Digit Verification of cas no
The CAS Registry Mumber 402820-94-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,2,8,2 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 402820-94:
(8*4)+(7*0)+(6*2)+(5*8)+(4*2)+(3*0)+(2*9)+(1*4)=114
114 % 10 = 4
So 402820-94-4 is a valid CAS Registry Number.
