Check Digit Verification of cas no
The CAS Registry Mumber 201231-48-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,2,3 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 201231-48:
(8*2)+(7*0)+(6*1)+(5*2)+(4*3)+(3*1)+(2*4)+(1*8)=63
63 % 10 = 3
So 201231-48-3 is a valid CAS Registry Number.
