Check Digit Verification of cas no
The CAS Registry Mumber 847923-54-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,7,9,2 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 847923-54:
(8*8)+(7*4)+(6*7)+(5*9)+(4*2)+(3*3)+(2*5)+(1*4)=210
210 % 10 = 0
So 847923-54-0 is a valid CAS Registry Number.
