Check Digit Verification of cas no
The CAS Registry Mumber 2379-75-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,7 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2379-75:
(6*2)+(5*3)+(4*7)+(3*9)+(2*7)+(1*5)=101
101 % 10 = 1
So 2379-75-1 is a valid CAS Registry Number.
