Check Digit Verification of cas no
The CAS Registry Mumber 1607805-99-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,7,8,0 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1607805-99:
(9*1)+(8*6)+(7*0)+(6*7)+(5*8)+(4*0)+(3*5)+(2*9)+(1*9)=181
