139477-52-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139477-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,7 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139477-52:
(8*1)+(7*3)+(6*9)+(5*4)+(4*7)+(3*7)+(2*5)+(1*2)=164
164 % 10 = 4
So 139477-52-4 is a valid CAS Registry Number.

, p. 5961 - 5968 (1993)
The pheromones (1a,1b) of two insect pests, the Japanese Beetle (Popillia japonica, Newman) and Cupreus Chafer Beetle (Anomala cuprea, Hope), were synthesized. Starting from protected D-Ribose, 1a was prepared in 8 steps with a 30% total yield. The same chemistry was demonstrated for the synthesis of 1b.
