Check Digit Verification of cas no
The CAS Registry Mumber 66605-92-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,0 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 66605-92:
(7*6)+(6*6)+(5*6)+(4*0)+(3*5)+(2*9)+(1*2)=143
143 % 10 = 3
