123558-58-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123558-58-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,5,5 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123558-58:
(8*1)+(7*2)+(6*3)+(5*5)+(4*5)+(3*8)+(2*5)+(1*8)=127
127 % 10 = 7
So 123558-58-7 is a valid CAS Registry Number.
