Check Digit Verification of cas no
The CAS Registry Mumber 893729-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,3,7,2 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 893729-04:
(8*8)+(7*9)+(6*3)+(5*7)+(4*2)+(3*9)+(2*0)+(1*4)=219
219 % 10 = 9
