108340-97-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108340-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,3,4 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 108340-97:
(8*1)+(7*0)+(6*8)+(5*3)+(4*4)+(3*0)+(2*9)+(1*7)=112
112 % 10 = 2
So 108340-97-2 is a valid CAS Registry Number.
