1556-30-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1556-30-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1556-30:
(6*1)+(5*5)+(4*5)+(3*6)+(2*3)+(1*0)=75
75 % 10 = 5
So 1556-30-5 is a valid CAS Registry Number.
