Check Digit Verification of cas no
The CAS Registry Mumber 199478-32-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,4,7 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 199478-32:
(8*1)+(7*9)+(6*9)+(5*4)+(4*7)+(3*8)+(2*3)+(1*2)=205
205 % 10 = 5
