131471-29-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131471-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,7 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131471-29:
(8*1)+(7*3)+(6*1)+(5*4)+(4*7)+(3*1)+(2*2)+(1*9)=99
99 % 10 = 9
So 131471-29-9 is a valid CAS Registry Number.
