138682-16-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138682-16-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,8 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138682-16:
(8*1)+(7*3)+(6*8)+(5*6)+(4*8)+(3*2)+(2*1)+(1*6)=153
153 % 10 = 3
So 138682-16-3 is a valid CAS Registry Number.
