Check Digit Verification of cas no
The CAS Registry Mumber 1562-85-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,6 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1562-85:
(6*1)+(5*5)+(4*6)+(3*2)+(2*8)+(1*5)=82
82 % 10 = 2
So 1562-85-2 is a valid CAS Registry Number.
