Check Digit Verification of cas no
The CAS Registry Mumber 5601-29-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,0 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5601-29:
(6*5)+(5*6)+(4*0)+(3*1)+(2*2)+(1*9)=76
76 % 10 = 6
So 5601-29-6 is a valid CAS Registry Number.
