Check Digit Verification of cas no
The CAS Registry Mumber 676647-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,6,6,4 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 676647-59:
(8*6)+(7*7)+(6*6)+(5*6)+(4*4)+(3*7)+(2*5)+(1*9)=219
219 % 10 = 9
So 676647-59-9 is a valid CAS Registry Number.
