660437-52-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 660437-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,0,4,3 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 660437-52:
(8*6)+(7*6)+(6*0)+(5*4)+(4*3)+(3*7)+(2*5)+(1*2)=155
155 % 10 = 5
So 660437-52-5 is a valid CAS Registry Number.
