Check Digit Verification of cas no
The CAS Registry Mumber 177981-47-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,9,8 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 177981-47:
(8*1)+(7*7)+(6*7)+(5*9)+(4*8)+(3*1)+(2*4)+(1*7)=194
194 % 10 = 4
So 177981-47-4 is a valid CAS Registry Number.
