7355-42-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7355-42-2 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, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7355-42:
(6*7)+(5*3)+(4*5)+(3*5)+(2*4)+(1*2)=102
102 % 10 = 2
So 7355-42-2 is a valid CAS Registry Number.
