Check Digit Verification of cas no
The CAS Registry Mumber 436101-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,6,1,0 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 436101-49:
(8*4)+(7*3)+(6*6)+(5*1)+(4*0)+(3*1)+(2*4)+(1*9)=114
114 % 10 = 4
