120931-57-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120931-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,9,3 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 120931-57:
(8*1)+(7*2)+(6*0)+(5*9)+(4*3)+(3*1)+(2*5)+(1*7)=99
99 % 10 = 9
So 120931-57-9 is a valid CAS Registry Number.
