1313188-51-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1313188-51-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,1,8 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1313188-51:
(9*1)+(8*3)+(7*1)+(6*3)+(5*1)+(4*8)+(3*8)+(2*5)+(1*1)=130
130 % 10 = 0
So 1313188-51-0 is a valid CAS Registry Number.
