2542-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2542-99-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,4 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.Calculate Digit Verification of CAS Registry Number 2542-99:
(6*2)+(5*5)+(4*4)+(3*2)+(2*9)+(1*9)=86
86 % 10 = 6
So 2542-99-6 is a valid CAS Registry Number.
