Check Digit Verification of cas no
The CAS Registry Mumber 275805-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,5,8,0 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 275805-33:
(8*2)+(7*7)+(6*5)+(5*8)+(4*0)+(3*5)+(2*3)+(1*3)=159
159 % 10 = 9
