Check Digit Verification of cas no
The CAS Registry Mumber 180748-12-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,7,4 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 180748-12:
(8*1)+(7*8)+(6*0)+(5*7)+(4*4)+(3*8)+(2*1)+(1*2)=143
143 % 10 = 3
So 180748-12-3 is a valid CAS Registry Number.
