958-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 958-55-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,5 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.Calculate Digit Verification of CAS Registry Number 958-55:
(5*9)+(4*5)+(3*8)+(2*5)+(1*5)=104
104 % 10 = 4
So 958-55-4 is a valid CAS Registry Number.
