Check Digit Verification of cas no
The CAS Registry Mumber 183555-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,5,5 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 183555-52:
(8*1)+(7*8)+(6*3)+(5*5)+(4*5)+(3*5)+(2*5)+(1*2)=154
154 % 10 = 4
