Check Digit Verification of cas no
The CAS Registry Mumber 349557-40-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,9,5,5 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 349557-40:
(8*3)+(7*4)+(6*9)+(5*5)+(4*5)+(3*7)+(2*4)+(1*0)=180
180 % 10 = 0
