13577-08-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13577-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,7 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13577-08:
(7*1)+(6*3)+(5*5)+(4*7)+(3*7)+(2*0)+(1*8)=107
107 % 10 = 7
So 13577-08-7 is a valid CAS Registry Number.
