208391-45-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 208391-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,3,9 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 208391-45:
(8*2)+(7*0)+(6*8)+(5*3)+(4*9)+(3*1)+(2*4)+(1*5)=131
131 % 10 = 1
So 208391-45-1 is a valid CAS Registry Number.
