147555-67-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 147555-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,5,5 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 147555-67:
(8*1)+(7*4)+(6*7)+(5*5)+(4*5)+(3*5)+(2*6)+(1*7)=157
157 % 10 = 7
So 147555-67-7 is a valid CAS Registry Number.
