120286-11-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120286-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,2,8 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 120286-11:
(8*1)+(7*2)+(6*0)+(5*2)+(4*8)+(3*6)+(2*1)+(1*1)=85
85 % 10 = 5
So 120286-11-5 is a valid CAS Registry Number.
