138921-17-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138921-17-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,2 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138921-17:
(8*1)+(7*3)+(6*8)+(5*9)+(4*2)+(3*1)+(2*1)+(1*7)=142
142 % 10 = 2
So 138921-17-2 is a valid CAS Registry Number.
