857808-32-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 857808-32-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,8,0 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 857808-32:
(8*8)+(7*5)+(6*7)+(5*8)+(4*0)+(3*8)+(2*3)+(1*2)=213
213 % 10 = 3
So 857808-32-3 is a valid CAS Registry Number.
