1313271-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1313271-76-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,2,7 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1313271-76:
(9*1)+(8*3)+(7*1)+(6*3)+(5*2)+(4*7)+(3*1)+(2*7)+(1*6)=119
119 % 10 = 9
So 1313271-76-9 is a valid CAS Registry Number.
