Check Digit Verification of cas no
The CAS Registry Mumber 120951-69-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,9,5 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120951-69:
(8*1)+(7*2)+(6*0)+(5*9)+(4*5)+(3*1)+(2*6)+(1*9)=111
111 % 10 = 1
So 120951-69-1 is a valid CAS Registry Number.
