Check Digit Verification of cas no
The CAS Registry Mumber 206444-58-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,4,4 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 206444-58:
(8*2)+(7*0)+(6*6)+(5*4)+(4*4)+(3*4)+(2*5)+(1*8)=118
118 % 10 = 8
So 206444-58-8 is a valid CAS Registry Number.
