Check Digit Verification of cas no
The CAS Registry Mumber 6406-38-8 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, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6406-38:
(6*6)+(5*4)+(4*0)+(3*6)+(2*3)+(1*8)=88
88 % 10 = 8
So 6406-38-8 is a valid CAS Registry Number.
