1394138-42-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1394138-42-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,4,1,3 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1394138-42:
(9*1)+(8*3)+(7*9)+(6*4)+(5*1)+(4*3)+(3*8)+(2*4)+(1*2)=171
171 % 10 = 1
So 1394138-42-1 is a valid CAS Registry Number.
