137411-29-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137411-29-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,1 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137411-29:
(8*1)+(7*3)+(6*7)+(5*4)+(4*1)+(3*1)+(2*2)+(1*9)=111
111 % 10 = 1
So 137411-29-1 is a valid CAS Registry Number.
