Check Digit Verification of cas no
The CAS Registry Mumber 121054-10-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,5 and 4 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121054-10:
(8*1)+(7*2)+(6*1)+(5*0)+(4*5)+(3*4)+(2*1)+(1*0)=62
62 % 10 = 2
So 121054-10-2 is a valid CAS Registry Number.
