Check Digit Verification of cas no
The CAS Registry Mumber 1643156-18-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,3,1,5 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1643156-18:
(9*1)+(8*6)+(7*4)+(6*3)+(5*1)+(4*5)+(3*6)+(2*1)+(1*8)=156
156 % 10 = 6
So 1643156-18-6 is a valid CAS Registry Number.
