Check Digit Verification of cas no
The CAS Registry Mumber 1645-93-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1645-93:
(6*1)+(5*6)+(4*4)+(3*5)+(2*9)+(1*3)=88
88 % 10 = 8
So 1645-93-8 is a valid CAS Registry Number.
