Check Digit Verification of cas no
The CAS Registry Mumber 3618-60-8 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 0 respectively.
Calculate Digit Verification of CAS Registry Number 3618-60:
(6*3)+(5*6)+(4*1)+(3*8)+(2*6)+(1*0)=88
88 % 10 = 8
So 3618-60-8 is a valid CAS Registry Number.
