147487-01-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 147487-01-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,4,8 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 147487-01:
(8*1)+(7*4)+(6*7)+(5*4)+(4*8)+(3*7)+(2*0)+(1*1)=152
152 % 10 = 2
So 147487-01-2 is a valid CAS Registry Number.
