Check Digit Verification of cas no
The CAS Registry Mumber 1562-90-9 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, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1562-90:
(6*1)+(5*5)+(4*6)+(3*2)+(2*9)+(1*0)=79
79 % 10 = 9
So 1562-90-9 is a valid CAS Registry Number.
