33080-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33080-87-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,0,8 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 33080-87:
(7*3)+(6*3)+(5*0)+(4*8)+(3*0)+(2*8)+(1*7)=94
94 % 10 = 4
So 33080-87-4 is a valid CAS Registry Number.
