485808-33-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 485808-33-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,8,5,8,0 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 485808-33:
(8*4)+(7*8)+(6*5)+(5*8)+(4*0)+(3*8)+(2*3)+(1*3)=191
191 % 10 = 1
So 485808-33-1 is a valid CAS Registry Number.
