Check Digit Verification of cas no
The CAS Registry Mumber 157057-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,0,5 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 157057-20:
(8*1)+(7*5)+(6*7)+(5*0)+(4*5)+(3*7)+(2*2)+(1*0)=130
130 % 10 = 0
So 157057-20-0 is a valid CAS Registry Number.
