138286-15-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138286-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,8 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138286-15:
(8*1)+(7*3)+(6*8)+(5*2)+(4*8)+(3*6)+(2*1)+(1*5)=144
144 % 10 = 4
So 138286-15-4 is a valid CAS Registry Number.
