103897-29-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103897-29-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,8,9 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 103897-29:
(8*1)+(7*0)+(6*3)+(5*8)+(4*9)+(3*7)+(2*2)+(1*9)=136
136 % 10 = 6
So 103897-29-6 is a valid CAS Registry Number.
