1311971-54-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1311971-54-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,1,9,7 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1311971-54:
(9*1)+(8*3)+(7*1)+(6*1)+(5*9)+(4*7)+(3*1)+(2*5)+(1*4)=136
136 % 10 = 6
So 1311971-54-6 is a valid CAS Registry Number.
