Check Digit Verification of cas no
The CAS Registry Mumber 3618-63-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,1 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3618-63:
(6*3)+(5*6)+(4*1)+(3*8)+(2*6)+(1*3)=91
91 % 10 = 1
So 3618-63-1 is a valid CAS Registry Number.
