1313222-58-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1313222-58-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,2,2 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1313222-58:
(9*1)+(8*3)+(7*1)+(6*3)+(5*2)+(4*2)+(3*2)+(2*5)+(1*8)=100
100 % 10 = 0
So 1313222-58-0 is a valid CAS Registry Number.
