107680-85-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107680-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,6,8 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 107680-85:
(8*1)+(7*0)+(6*7)+(5*6)+(4*8)+(3*0)+(2*8)+(1*5)=133
133 % 10 = 3
So 107680-85-3 is a valid CAS Registry Number.
