Check Digit Verification of cas no
The CAS Registry Mumber 676562-71-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,6,5,6 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 676562-71:
(8*6)+(7*7)+(6*6)+(5*5)+(4*6)+(3*2)+(2*7)+(1*1)=203
203 % 10 = 3
So 676562-71-3 is a valid CAS Registry Number.
