Check Digit Verification of cas no
The CAS Registry Mumber 6226-70-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,2 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6226-70:
(6*6)+(5*2)+(4*2)+(3*6)+(2*7)+(1*0)=86
86 % 10 = 6
So 6226-70-6 is a valid CAS Registry Number.
