Check Digit Verification of cas no
The CAS Registry Mumber 21934-68-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,3 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21934-68:
(7*2)+(6*1)+(5*9)+(4*3)+(3*4)+(2*6)+(1*8)=109
109 % 10 = 9
So 21934-68-9 is a valid CAS Registry Number.
