138478-71-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138478-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,7 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138478-71:
(8*1)+(7*3)+(6*8)+(5*4)+(4*7)+(3*8)+(2*7)+(1*1)=164
164 % 10 = 4
So 138478-71-4 is a valid CAS Registry Number.
