131548-29-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131548-29-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,4 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131548-29:
(8*1)+(7*3)+(6*1)+(5*5)+(4*4)+(3*8)+(2*2)+(1*9)=113
113 % 10 = 3
So 131548-29-3 is a valid CAS Registry Number.
