1381843-47-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1381843-47-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,1,8,4 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1381843-47:
(9*1)+(8*3)+(7*8)+(6*1)+(5*8)+(4*4)+(3*3)+(2*4)+(1*7)=175
175 % 10 = 5
So 1381843-47-5 is a valid CAS Registry Number.
