Check Digit Verification of cas no
The CAS Registry Mumber 23894-07-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,8,9 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 23894-07:
(7*2)+(6*3)+(5*8)+(4*9)+(3*4)+(2*0)+(1*7)=127
127 % 10 = 7
So 23894-07-7 is a valid CAS Registry Number.
