Check Digit Verification of cas no
The CAS Registry Mumber 437606-60-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,7,6,0 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 437606-60:
(8*4)+(7*3)+(6*7)+(5*6)+(4*0)+(3*6)+(2*6)+(1*0)=155
155 % 10 = 5
So 437606-60-5 is a valid CAS Registry Number.
