Check Digit Verification of cas no
The CAS Registry Mumber 20486-07-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,8 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20486-07:
(7*2)+(6*0)+(5*4)+(4*8)+(3*6)+(2*0)+(1*7)=91
91 % 10 = 1
So 20486-07-1 is a valid CAS Registry Number.
