Check Digit Verification of cas no
The CAS Registry Mumber 934623-81-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,4,6,2 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 934623-81:
(8*9)+(7*3)+(6*4)+(5*6)+(4*2)+(3*3)+(2*8)+(1*1)=181
181 % 10 = 1
