100556-03-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 100556-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,5,5 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 100556-03:
(8*1)+(7*0)+(6*0)+(5*5)+(4*5)+(3*6)+(2*0)+(1*3)=74
74 % 10 = 4
So 100556-03-4 is a valid CAS Registry Number.
