33204-37-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33204-37-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,0 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 33204-37:
(7*3)+(6*3)+(5*2)+(4*0)+(3*4)+(2*3)+(1*7)=74
74 % 10 = 4
So 33204-37-4 is a valid CAS Registry Number.
