120385-63-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120385-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,3,8 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 120385-63:
(8*1)+(7*2)+(6*0)+(5*3)+(4*8)+(3*5)+(2*6)+(1*3)=99
99 % 10 = 9
So 120385-63-9 is a valid CAS Registry Number.
