1519-56-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1519-56-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,1 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.Calculate Digit Verification of CAS Registry Number 1519-56:
(6*1)+(5*5)+(4*1)+(3*9)+(2*5)+(1*6)=78
78 % 10 = 8
So 1519-56-8 is a valid CAS Registry Number.
