134478-31-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134478-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,4,7 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 134478-31:
(8*1)+(7*3)+(6*4)+(5*4)+(4*7)+(3*8)+(2*3)+(1*1)=132
132 % 10 = 2
So 134478-31-2 is a valid CAS Registry Number.
