Check Digit Verification of cas no
The CAS Registry Mumber 235779-10-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,5,7,7 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 235779-10:
(8*2)+(7*3)+(6*5)+(5*7)+(4*7)+(3*9)+(2*1)+(1*0)=159
159 % 10 = 9
So 235779-10-9 is a valid CAS Registry Number.
