Check Digit Verification of cas no
The CAS Registry Mumber 131423-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,2 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131423-71:
(8*1)+(7*3)+(6*1)+(5*4)+(4*2)+(3*3)+(2*7)+(1*1)=87
87 % 10 = 7
So 131423-71-7 is a valid CAS Registry Number.
