Check Digit Verification of cas no
The CAS Registry Mumber 438246-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,8,2,4 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 438246-20:
(8*4)+(7*3)+(6*8)+(5*2)+(4*4)+(3*6)+(2*2)+(1*0)=149
149 % 10 = 9
So 438246-20-9 is a valid CAS Registry Number.
