138202-14-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138202-14-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,0 and 2 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138202-14:
(8*1)+(7*3)+(6*8)+(5*2)+(4*0)+(3*2)+(2*1)+(1*4)=99
99 % 10 = 9
So 138202-14-9 is a valid CAS Registry Number.
