Check Digit Verification of cas no
The CAS Registry Mumber 6621-62-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,2 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6621-62:
(6*6)+(5*6)+(4*2)+(3*1)+(2*6)+(1*2)=91
91 % 10 = 1
So 6621-62-1 is a valid CAS Registry Number.
