337963-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 337963-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,7,9,6 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 337963-33:
(8*3)+(7*3)+(6*7)+(5*9)+(4*6)+(3*3)+(2*3)+(1*3)=174
174 % 10 = 4
So 337963-33-4 is a valid CAS Registry Number.
