857681-75-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 857681-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,6,8 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 857681-75:
(8*8)+(7*5)+(6*7)+(5*6)+(4*8)+(3*1)+(2*7)+(1*5)=225
225 % 10 = 5
So 857681-75-5 is a valid CAS Registry Number.
