107235-69-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107235-69-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,2,3 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 107235-69:
(8*1)+(7*0)+(6*7)+(5*2)+(4*3)+(3*5)+(2*6)+(1*9)=108
108 % 10 = 8
So 107235-69-8 is a valid CAS Registry Number.
