2241-59-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2241-59-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,4 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2241-59:
(6*2)+(5*2)+(4*4)+(3*1)+(2*5)+(1*9)=60
60 % 10 = 0
So 2241-59-0 is a valid CAS Registry Number.
