7355-35-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7355-35-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,5 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.Calculate Digit Verification of CAS Registry Number 7355-35:
(6*7)+(5*3)+(4*5)+(3*5)+(2*3)+(1*5)=103
103 % 10 = 3
So 7355-35-3 is a valid CAS Registry Number.
