Check Digit Verification of cas no
The CAS Registry Mumber 660424-65-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,0,4,2 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 660424-65:
(8*6)+(7*6)+(6*0)+(5*4)+(4*2)+(3*4)+(2*6)+(1*5)=147
147 % 10 = 7
So 660424-65-7 is a valid CAS Registry Number.
