Check Digit Verification of cas no
The CAS Registry Mumber 7219-11-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,1 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7219-11:
(6*7)+(5*2)+(4*1)+(3*9)+(2*1)+(1*1)=86
86 % 10 = 6
So 7219-11-6 is a valid CAS Registry Number.
