138200-29-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138200-29-0 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 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138200-29:
(8*1)+(7*3)+(6*8)+(5*2)+(4*0)+(3*0)+(2*2)+(1*9)=100
100 % 10 = 0
So 138200-29-0 is a valid CAS Registry Number.
