Check Digit Verification of cas no
The CAS Registry Mumber 6406-61-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6406-61:
(6*6)+(5*4)+(4*0)+(3*6)+(2*6)+(1*1)=87
87 % 10 = 7
So 6406-61-7 is a valid CAS Registry Number.
