Check Digit Verification of cas no
The CAS Registry Mumber 847983-10-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,7,9,8 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 847983-10:
(8*8)+(7*4)+(6*7)+(5*9)+(4*8)+(3*3)+(2*1)+(1*0)=222
222 % 10 = 2
So 847983-10-2 is a valid CAS Registry Number.
