209127-52-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 209127-52-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,1,2 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 209127-52:
(8*2)+(7*0)+(6*9)+(5*1)+(4*2)+(3*7)+(2*5)+(1*2)=116
116 % 10 = 6
So 209127-52-6 is a valid CAS Registry Number.
