Check Digit Verification of cas no
The CAS Registry Mumber 1021187-27-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,1,8 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1021187-27:
(9*1)+(8*0)+(7*2)+(6*1)+(5*1)+(4*8)+(3*7)+(2*2)+(1*7)=98
98 % 10 = 8
So 1021187-27-8 is a valid CAS Registry Number.
