211308-48-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 211308-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,3,0 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 211308-48:
(8*2)+(7*1)+(6*1)+(5*3)+(4*0)+(3*8)+(2*4)+(1*8)=84
84 % 10 = 4
So 211308-48-4 is a valid CAS Registry Number.
