Check Digit Verification of cas no
The CAS Registry Mumber 141989-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,9,8 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 141989-22:
(8*1)+(7*4)+(6*1)+(5*9)+(4*8)+(3*9)+(2*2)+(1*2)=152
152 % 10 = 2
So 141989-22-2 is a valid CAS Registry Number.
