206272-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 206272-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,2,7 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 206272-56:
(8*2)+(7*0)+(6*6)+(5*2)+(4*7)+(3*2)+(2*5)+(1*6)=112
112 % 10 = 2
So 206272-56-2 is a valid CAS Registry Number.
