Check Digit Verification of cas no
The CAS Registry Mumber 858421-10-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,4,2 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 858421-10:
(8*8)+(7*5)+(6*8)+(5*4)+(4*2)+(3*1)+(2*1)+(1*0)=180
180 % 10 = 0
So 858421-10-0 is a valid CAS Registry Number.
