137411-38-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137411-38-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,1 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 137411-38:
(8*1)+(7*3)+(6*7)+(5*4)+(4*1)+(3*1)+(2*3)+(1*8)=112
112 % 10 = 2
So 137411-38-2 is a valid CAS Registry Number.
