Check Digit Verification of cas no
The CAS Registry Mumber 138207-02-0 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 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138207-02:
(8*1)+(7*3)+(6*8)+(5*2)+(4*0)+(3*7)+(2*0)+(1*2)=110
110 % 10 = 0
So 138207-02-0 is a valid CAS Registry Number.
