Check Digit Verification of cas no
The CAS Registry Mumber 1000890-01-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,0,8,9 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1000890-01:
(9*1)+(8*0)+(7*0)+(6*0)+(5*8)+(4*9)+(3*0)+(2*0)+(1*1)=86
86 % 10 = 6
So 1000890-01-6 is a valid CAS Registry Number.
