Check Digit Verification of cas no
The CAS Registry Mumber 6844-74-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,4 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6844-74:
(6*6)+(5*8)+(4*4)+(3*4)+(2*7)+(1*4)=122
122 % 10 = 2
So 6844-74-2 is a valid CAS Registry Number.
